In the first days after birth, almost every new mother asks a version of the same question: is this amount of bleeding normal? It is a fair question, because nobody describes postpartum bleeding accurately beforehand. It is heavier than a period at the start, it changes colour in ways that can be alarming, it can pause and come back, and it behaves differently from one woman to the next. Most of that variation is entirely normal. A small part of it is not, and the difference matters, because bleeding after birth is one of the few postnatal problems that can become serious quickly.

This article explains what postpartum bleeding actually is, what the three stages of lochia look like week by week, how long it should last, what size of clot deserves a phone call, how a caesarean changes the picture, why bleeding sometimes stops and restarts, and when your periods are likely to return. Most importantly, it sets out clear thresholds: what to mention at your next appointment, what to telephone about today, and what means going to hospital now. Nothing here replaces being examined. If your instinct tells you something is wrong, that instinct is worth acting on.

What Postpartum Bleeding Is, and Why It Happens

Postpartum bleeding, known medically as lochia, is the discharge your body produces while the inside of the uterus heals after birth. It is not a period and it is not simply left-over blood. When the placenta separates, it leaves a raw area on the uterine wall roughly the size of your palm, crossed by open blood vessels. The uterus closes that area down by contracting hard, trapping and squeezing those vessels between its muscle fibres. Muscle tone, far more than clotting, is what stops the bleeding. This is why a well-contracted uterus feels firm like a grapefruit low in the abdomen in the first days, and why a soft, poorly contracted one bleeds.

Lochia is therefore a mixture rather than pure blood: blood from the placental bed, the shed inner lining of the pregnant uterus (the decidua), white blood cells clearing debris, mucus and cervical secretions. Its composition changes as healing progresses, and because the proportions change, so do the colour, the consistency and the volume. That is the whole logic behind the three stages described below.

Everyone bleeds after birth. A caesarean does not exempt you, because the lochia comes from the healing uterine lining and not from the vagina or the perineum. A straightforward birth is no guarantee of light lochia, and a long or complicated one does not automatically mean heavy lochia — the range overlaps a great deal. What is more useful than comparing birth stories is watching the direction your own loss is travelling in.

At the same time, the uterus is shrinking back, a process called involution. It goes from around a kilogram at delivery to roughly the size of a fist within six weeks, and it can usually no longer be felt above the pubic bone by around two weeks. Breastfeeding accelerates this, because suckling releases oxytocin and makes the uterus contract. Those contractions are the cramping many women feel during feeds in the first week, sometimes called afterpains, and they are often accompanied by a small gush of lochia. That is the system working, not a problem.

If you want the wider context of how pregnancy and the postnatal period are monitored, our overview of pregnancy follow-up and antenatal care explains what each stage of review is looking for. Women who had bleeding at some point during the pregnancy itself often ask whether the loss they are seeing now is connected to it, or whether it makes heavy postnatal bleeding more likely; the two are separate problems with separate causes, and our guide to bleeding during pregnancy and when to get help sets out what lies behind bleeding before birth.

The Three Stages of Lochia: Rubra, Serosa and Alba

Lochia passes through three recognised stages — rubra (red), serosa (pink-brown) and alba (cream-white) — and the direction of travel matters more than the exact timing. The loss should get lighter in colour, lighter in volume and thinner in consistency as the weeks pass. Going backwards, from pale to bright red and heavy, is the pattern that needs assessment.

Lochia rubra: roughly days 1 to 4

Dark red or brownish-red, the heaviest of the three, with a thicker consistency and often small clots. This is predominantly blood from the placental site, mixed with fragments of decidua and other debris from pregnancy. Expect to need maternity pads rather than ordinary sanitary towels, to change them every few hours, and to see a gush when you stand up after lying down — blood pools in the vagina while you are horizontal and simply runs out when you get up. The flow typically settles noticeably after the first 48 to 72 hours.

Lochia serosa: roughly days 4 to 10

Pink, pinkish-brown or watery brown, distinctly lighter and thinner. The red cell content is falling and serous fluid, white cells and cervical mucus make up more of the volume. By this stage most women are using one pad at a time rather than doubling up, and small clots should be becoming rare. Some women pass through this phase faster, some slower; a range of about four days to two weeks is unremarkable.

Lochia alba: roughly day 10 to week 4 to 6

Creamy white, pale yellow or very light beige, scant, and more like a discharge than a bleed. It is mostly white blood cells, decidual and epithelial cells, and mucus, with little blood. This last phase is the longest and the most variable. Many women find it tails off into ordinary discharge without a clear end point. If you are unsure whether what you are seeing is late lochia or something else, our guide to the different types of vaginal discharge covers what healthy discharge looks like outside pregnancy.

How Long Postpartum Bleeding Lasts

Most women bleed for between two and six weeks after birth, with four to six weeks being typical, and a light cream-coloured discharge sometimes persisting a little beyond that. There is no single correct duration. Stopping at two and a half weeks is not a sign that something was missed, and still having a scant pale loss at seven weeks is not automatically abnormal either.

What should be consistent is the trajectory. Heavy bright red loss belongs to the first few days. By the end of the first week it should be lighter and browner. By two weeks most women are on a pad or liner rather than maternity pads. By four weeks the loss is usually minimal. If any of those steps is not happening, or the pattern reverses, that is worth a call rather than a wait-and-see.

Several things genuinely influence the length. Breastfeeding tends to shorten it slightly because of the oxytocin effect on uterine contraction. Being very active early, lifting more than you should or returning to exercise quickly can make the loss heavier and longer. A long labour, a large baby, twins, a uterus that has been stretched by several previous pregnancies, or fibroids in the uterine wall can all mean a more prolonged loss, because the uterus has more work to do to contract down. None of these is a reason to expect a problem; they simply shift where you are likely to sit within the normal range.

The same healing pattern applies after a birth that came early, and after a pregnancy that ended later in its course, although both the volume and the duration tend to be smaller the earlier the pregnancy finished. The principle does not change: lighter and paler week by week, never the reverse.

Two patterns are not normal, regardless of the week: loss that stays as heavy as day one for more than a few days, and loss that remains frankly bright red and substantial after the first week to ten days. Both deserve examination rather than reassurance over the phone.

Week by Week: Normal Colour and Volume Changes

Here is the same timeline in a form you can scan. Use it as a reference point rather than a rule — being a few days ahead or behind on any line is common, and the stage descriptions above carry the detail.

• Days 1 to 4 (lochia rubra): dark red and heaviest; maternity pads, small clots and an obvious gush on standing are all expected.
• Days 4 to 6: red fading to dark red or brown, transitioning into lochia serosa; pad changes stretching further apart.
• Week 2 (lochia serosa): pink, brown or watery brown. A short-lived return of fresh red loss around days 7 to 14 is common and is explained below.
• Week 3 (early lochia alba): light brown or beige and scant; many women move to a liner at this point.
• Weeks 4 to 6 (lochia alba): cream, pale yellow or clear-white and minimal. Occasional days of nothing, then a little, as the last of the lining clears.
• After week 6: a scant pale discharge can continue in some women, but fresh red bleeding at this stage is either a returning period or something that needs checking.

Judging volume is genuinely difficult, and most women either over- or under-estimate. A practical measure is pad saturation over time rather than how dramatic a single episode looked. A pad that is partly stained after three or four hours in the first week is expected. A pad that is soaked through, front to back, in under an hour is not, at any stage.

A few everyday things also make the loss look worse than it is. Lying still for several hours lets blood pool, so the first trip to the bathroom after a nap often produces the biggest gush of the day. A feed triggers contractions, so it can be followed by a surge of loss and a cramp. Straining on the toilet, which is common in the first week because of constipation, can push out collected blood and a clot at once. None of these is bleeding that is getting worse — it is collected blood leaving at a predictable moment. What counts is the total over a whole day, and whether that total is smaller this week than last.

Smell matters too, and it is covered in the section on infection below.

Clots: What Size Is Concerning?

Small clots up to roughly the size of a grape are expected in the first few days; a clot the size of a golf ball or larger, or clots still arriving after the first week, should prompt a call. Most clots are simply blood that pooled and congealed in the vagina while you were lying still, then came away when you stood up or went to the toilet. That is why the biggest clot of the day is often the first one in the morning.

One size scale, so there is no guesswork:

• Expected in the first few days: occasional clots up to about the size of a grape or a 50p coin, roughly 2.5 cm across, usually on standing and often with a gush of fresh loss.
• Telephone the same day: any clot larger than a 50p coin, clots that keep coming after the first week, or clots with cramping that is getting worse rather than better.
• Go to hospital now: a clot the size of a golf ball, roughly 4 cm across, or larger, or several large clots one after another. The full list of emergency signs is in the final section of this article.

Context changes the meaning. A single large clot on day two, after which the bleeding settles and you feel well, is usually the uterus clearing itself. A large clot on day fourteen, with cramping, an offensive smell or a temperature, points towards retained placental tissue or infection and needs an examination and usually an ultrasound scan.

It is worth knowing what that scan can and cannot settle. The postnatal uterine cavity very often contains some material on ultrasound, and blood clot can look much like retained placental tissue. A scan is therefore read alongside your symptoms rather than on its own: a woman who feels well with settling loss is usually watched, while the same picture in a woman with heavy fresh bleeding, pain or fever is treated. This is why you may be asked to come back for a repeat scan rather than straight to a procedure.

One further point that is often missed: a clot can also be a cause rather than a result. Clot and tissue sitting inside the uterine cavity stop it from contracting down properly, which in turn causes more bleeding. This is why a doctor or midwife will feel your abdomen, rub up the uterus to encourage it to contract, and make sure your bladder is empty — a full bladder physically prevents the uterus from contracting well.

Postpartum Haemorrhage: Primary, Secondary and the Red Flags

Postpartum haemorrhage means excessive bleeding after birth, and it is divided by timing: primary within the first 24 hours, secondary from 24 hours up to 12 weeks. Heavy bleeding in the first 24 hours is common enough that every maternity unit is set up to watch for it, while late bleeding at home affects roughly one woman in a hundred. Both are treatable, and both depend on being recognised early. That is the single most important reason not to talk yourself out of making a phone call.

Primary postpartum haemorrhage (first 24 hours)

By convention, a loss of 500 ml or more within 24 hours of a vaginal birth is classed as a postpartum haemorrhage, and more than 1000 ml as a major one. These are definitions used to trigger a response, not predictions about how you will feel. Obstetric teams group the causes into four: tone (a uterus that is not contracting, by far the commonest), trauma (a tear in the perineum, vagina, cervix or, rarely, the uterus), tissue (placenta or membranes left behind) and thrombin (a problem with blood clotting). Because this period is almost always spent on a maternity unit, staff are watching for it: they check your pulse, blood pressure, the firmness of the uterus and the weight of your pads.

Management follows the cause. It may include medicines that make the uterus contract, such as oxytocin, ergometrine or misoprostol; tranexamic acid to support clotting; emptying the bladder with a catheter; manual compression or rubbing up the uterus; repair of a tear; examination under anaesthetic to remove retained tissue; a balloon placed inside the uterus to apply pressure; intravenous fluids and, if needed, a blood transfusion. These are described here so that the terms are familiar if you hear them, not as a menu to choose from.

Secondary (late) postpartum haemorrhage: 24 hours to 12 weeks

This is the one that happens at home, and so the one that depends on you noticing. It means abnormally heavy or fresh bleeding after the first day, and the usual causes are retained placental tissue, infection of the uterine lining (endometritis), or subinvolution of the placental site, where the vessels at the placental bed fail to close down properly. Rarer causes include a vascular abnormality in the uterine wall or, very occasionally, persistent trophoblastic tissue.

Typically a woman is two to three weeks after birth, the lochia had been settling, and then the loss turns bright red and becomes as heavy as a period or heavier. There may be cramping, an offensive smell, a temperature, or none of these. Assessment usually involves examining the abdomen and uterus, a speculum examination, swabs, blood tests and a pelvic ultrasound scan to look for retained tissue. Treatment depends on what is found: antibiotics for infection, uterotonic medication, and sometimes a surgical procedure under anaesthetic to empty the uterine cavity.

Not every late bleed turns out to be a haemorrhage. Many are the brief separation of the crust over the placental site, a response to a busy day, or a first period arriving earlier than expected. The reason to be seen rather than reassured by telephone is simply that those possibilities cannot be separated from retained tissue or infection by description alone.

The signs that mean going to hospital rather than telephoning are set out in full in the final section of this article. If you are bleeding heavily while waiting for help, lie down, keep the pad you have used so the volume can be assessed, and do not drive yourself.

Bleeding After Caesarean Versus Vaginal Birth

Lochia happens after a caesarean just as it does after a vaginal birth, and it lasts for broadly the same length of time, because it comes from the healing uterine lining either way. The common assumption that a caesarean means no bleeding is one of the most frequent surprises in the first week.

There are real differences, though. The initial volume is sometimes a little lower in the first day or two, because the uterine cavity is wiped and cleared during the operation itself. Many women then notice a more obvious loss once they begin moving about, which can feel like a sudden deterioration but is usually just blood that had collected while they were lying still. Afterpains tend to be less noticeable in the first days because of the pain relief being used for the wound, and more noticeable once that is reduced.

A caesarean also adds a second site to watch. The abdominal wound should become less, not more, painful, and the skin around it should not be increasingly red, hot, swollen or leaking fluid. Fresh bleeding from the wound itself, or a rapidly enlarging firm swelling under it, needs to be seen the same day. After a vaginal birth, the equivalent watch point is the perineum: bleeding directly from a tear or stitches, which you can often identify because it is bright red and increases when you move or strain, is different from lochia coming from the uterus, and a stitch that gives way or a swelling that becomes severely painful needs review.

Two further things are worth saying about the first fortnight after a caesarean. Moving about early, within the limits of your pain relief, is encouraged partly because it reduces the risk of a blood clot in the leg, and some women are given blood-thinning injections to use at home for the same reason; neither of these makes your lochia heavier. And the loss is harder to judge while you are also managing a dressing and a sore abdomen, so it is worth actually looking at the pad rather than going by how you feel.

Later on, some women who have had a caesarean notice brownish spotting that drags on for weeks, or that reappears at the end of each period once cycles return. A small pouch can form in the scar on the inner surface of the uterus, where a little old blood collects and drains slowly. It is diagnosed on scan, it is often of no consequence, and it is only treated if it is causing troublesome bleeding or fertility problems. It is worth mentioning at your postnatal check rather than tolerating indefinitely.

When Bleeding Stops and Then Starts Again

A pause followed by a return of red loss around days 7 to 14 is common and usually harmless: the crust over the healing placental site separates at about that time, releasing a short-lived flow of fresh blood. It typically lasts a day or two, is not accompanied by feeling unwell, and then settles back to the pale loss it interrupted. Many women are told nothing about this and understandably assume something has gone wrong.

The other common innocent explanation is activity. A day of more walking than usual, a long trip, lifting a toddler, or starting exercise again often produces a day of heavier, redder loss. The body is giving feedback: do slightly less for a few days and it generally settles. This is also why your lochia may be heavier on the day you first leave the house than on the days before it.

Later on, bleeding that restarts after the loss had fully stopped is often simply the first period. If your lochia finished at four weeks and you have bright red bleeding at eight weeks that behaves like a period and lasts a few days, that is the most likely explanation, particularly if you are not breastfeeding exclusively.

What makes a stop-start pattern concerning is the company it keeps. Seek assessment if the returning bleeding is heavy rather than a day of spotting, if it is bright red and continuing rather than brief, if it smells offensive, if you have a temperature, chills or worsening abdominal pain, if it keeps recurring over several weeks, or if you feel unwell or faint with it. Those features point towards retained tissue or endometritis rather than normal healing, and both are straightforward to investigate.

Smell, Infection and Endometritis of the Uterus

Normal lochia smells stale and faintly metallic, like period blood; an offensive or foul smell is a sign of infection and should be reported the same day. Infection of the uterine lining after birth, endometritis, is the condition most often behind it.

The features to look for together, rather than in isolation, are: a temperature of 38°C or above, or recurrent chills and shivering; lochia with a strong unpleasant odour; lower abdominal pain or a uterus that is tender when you press on it; loss that becomes heavier or redder again instead of lighter; and simply feeling unwell, achy and flu-like. Infection is more likely after a caesarean, after prolonged rupture of the membranes, after a long labour with many examinations, if the placenta had to be removed manually, or if tissue was retained.

Because fever after birth has several possible sources, assessment looks wider than the uterus: the breasts for mastitis, the urinary tract for a bladder or kidney infection, the caesarean wound or perineal repair for a wound infection, the chest, and the legs for a clot. A blood clot in the leg or lung is a separate but important postnatal risk, so one-sided calf pain or swelling, or sudden breathlessness or chest pain, needs emergency assessment whether or not you have any bleeding.

Treatment of endometritis involves antibiotics, usually broad-spectrum and sometimes given intravenously at first, along with swabs and blood tests to guide them, and an ultrasound scan if retained tissue is suspected. If tissue is confirmed and bleeding persists, the cavity may need to be emptied surgically. Most women are safe to continue breastfeeding, and your doctor will choose antibiotics with that in mind. Do not wait for a second symptom to appear before telephoning: a bad smell alone is enough reason to be assessed.

Feeling generally unwell after birth is the starting point for one more condition that belongs in the same conversation, because blood pressure problems do not end at delivery. A severe headache, visual disturbance such as flashing lights or blurring, pain under the ribs on the right side, or sudden swelling of the face and hands in the days or weeks after birth can indicate postnatal preeclampsia, whose signs and risks every new mother should know. It is a medical emergency, and it is assessed in the same place you would go for heavy bleeding.

When Your Periods Come Back, and What Breastfeeding Changes

If you are not breastfeeding, your first period usually arrives somewhere between about four and twelve weeks after birth; if you are breastfeeding exclusively, it is commonly delayed for several months and sometimes until you reduce feeds or wean. Mixed feeding sits somewhere in between and is unpredictable.

The mechanism is straightforward. Frequent suckling keeps prolactin high, which suppresses the hormonal signals from the brain that drive ovulation. The more often and more exclusively you feed, including at night, the stronger that suppression. As feeds become less frequent, as the baby starts solids, or as night gaps lengthen, ovulation returns — often before you notice any other change.

That last point is the one to act on. Ovulation can happen before your first period, so it is possible to conceive while you still think you are protected. Breastfeeding on its own is only a reasonable contraceptive while three conditions all hold: the baby is under six months, you are fully or nearly fully breastfeeding day and night with no long gaps, and your periods have not returned. If any of those stops being true, you need another method. Contraception can usually be started in the early postnatal period, and the options discussed will take breastfeeding into account — progestogen-only pills, the implant and the injection are all compatible, and an intrauterine device or hormonal coil can be fitted either within the first 48 hours after birth or from about four weeks onwards. Our guide to IUD types, insertion and side effects explains what fitting involves.

Telling a first period apart from lochia is usually a matter of pattern. Lochia fades and thins without a clear end; a period starts after the loss has genuinely stopped, builds over a day or two, lasts a few days and then finishes. A new red bleed at five or six weeks, after the lochia had settled, is far more likely to be a period than a problem.

The first few periods after birth are frequently not what you remember. They may be heavier or lighter than before, longer, shorter, more painful or less, and the first two or three cycles may be irregular or spaced oddly before settling. Women who had very painful periods before pregnancy sometimes find them easier afterwards, and others find the opposite. Give it three or four cycles before drawing conclusions. If the irregularity persists beyond that, or bleeding is heavy enough to affect your daily life, it is worth investigating rather than attributing to motherhood — our article on the causes of irregular periods and when to worry covers what is looked for.

Looking After Yourself While You Are Bleeding

The practical priorities are simple: use pads rather than anything internal, change them regularly, keep your bladder empty, and do less than you think you can.

• Pads, not tampons or menstrual cups. Anything internal raises the risk of carrying bacteria into a healing uterus. Wait until the bleeding has finished and you have been reviewed, usually around six weeks.
• Change pads every few hours even when the loss is light, and wash your hands before and after. Do not douche or use internal washes; the vagina does not need them and they disturb its own balance.
• Empty your bladder regularly. A full bladder physically stops the uterus from contracting down and makes bleeding heavier. In the first days, go even if you do not feel the urge.
• Shower rather than soak in the first week or two if you have stitches, and avoid swimming pools until the bleeding has stopped.
• Eat and drink with the blood loss in mind. Iron-rich food, plenty of fluid and not skipping meals all help recovery; if you were taking iron in pregnancy, ask whether to continue it.
• Keep an eye on anaemia. Breathlessness on the stairs, a pounding heart, persistent dizziness, pallor or exhaustion beyond ordinary newborn tiredness after a heavy loss should be checked with a blood count; iron may be needed.
• Start pelvic-floor exercises when you feel able. They are safe while you are still bleeding and they do not make the loss heavier.
• Pace your activity. If the loss gets heavier or redder after a busy day, treat it as information and scale back for a few days.

On resuming sex: there is no fixed date, but wait until the bleeding has stopped, any stitches have healed and you feel physically and emotionally ready. Many women are reviewed at around six weeks and take their lead from that. Bleeding or significant pain with sex afterwards is not something to endure quietly — it is usually treatable, and it is a routine thing to raise.

Finally, keep the appointment for your postnatal check even if you feel well. It is the natural point to review bleeding that has not fully settled, discuss contraception, check blood pressure, look at the wound or repair, screen for low mood, and talk about the pelvic floor.

When to Call Your Midwife and When to Go Straight to Hospital

Use two thresholds: things to telephone about today, and things that mean emergency care now. If you are ever unsure which list you are in, assume the more urgent one. No maternity service minds being contacted about bleeding after birth.

Telephone your midwife or doctor the same day if

• The loss smells offensive or foul.
• You have a temperature of 38°C or above, chills or shivering.
• The bleeding is getting heavier instead of lighter, or has turned red again and stayed that way.
• You are still passing clots after the first week, or passing a clot larger than a 50p coin.
• Abdominal or pelvic pain is worsening rather than easing, or your uterus is tender to press.
• You are soaking a maternity pad every two to three hours beyond the first few days.
• Lochia that has never settled is still clearly red beyond six weeks (a distinct bleed starting after the loss had fully stopped is more likely to be a period).
• Your caesarean wound or perineal stitches are increasingly painful, red, swollen or leaking.

Go to hospital or call emergency services now if

• You soak more than one maternity pad in an hour, or a pad is soaked through within 15 minutes.
• You pass a clot the size of a golf ball or larger, or several large clots one after another.
• You feel faint, dizzy, cold, clammy, shaky, confused or are close to passing out.
• Your heart is racing or pounding, or you are unusually breathless.
• You have severe abdominal pain, or pain that comes on suddenly and does not ease.
• You have one-sided calf pain or swelling, chest pain or sudden breathlessness.
• You have a severe headache with visual disturbance, or sudden marked swelling of the face and hands.

Two habits make all of this easier. First, keep a rough mental note of how many pads you have changed and how wet they were; that single piece of information is more useful to a clinician than any description of how the bleeding looked. Second, do not compare yourself with other mothers. Their lochia tells you nothing about yours.

Bleeding after birth is a wound healing, and wounds heal on their own schedule. The reassuring part is that the normal pattern is genuinely predictable — lighter, paler, thinner, week by week — and that almost everything which goes wrong declares itself by breaking that pattern. If your loss is moving in the right direction and you feel well, you are almost certainly fine. If it reverses, smells wrong, or comes with fever or faintness, be examined.
