What Is Lochia and Why Does It Happen?

After giving birth — whether vaginally or by caesarean section — the body undergoes a significant process of shedding the uterine lining that built up over nine months of pregnancy. This discharge is called lochia. It consists of blood, mucus, white blood cells, and fragments of uterine tissue as the womb contracts back toward its pre-pregnancy size and sheds the material it no longer needs.

The word "lochia" comes from the Greek word for relating to childbirth, and it has been recognised as a normal part of postpartum recovery throughout recorded medical history. The NHS notes that lochia is expected in all women after birth — there is no way to avoid it, and trying to suppress it (for example by using tampons or menstrual cups) is actively harmful in the early weeks.

Understanding what lochia should look like at each stage, and what signals warrant urgent attention, is one of the most practically useful pieces of knowledge for the postnatal period.

The Three Phases of Lochia

Lochia Rubra: Days 1 to 4

In the first few days after birth, lochia is bright red and relatively heavy. This phase — called lochia rubra — reflects the active shedding of blood-rich uterine lining and the wound left where the placenta was attached to the uterine wall. It resembles a heavy period, though it is typically heavier than most people's usual menstruation.

During lochia rubra it is normal to pass small blood clots, particularly when first getting up after lying down or when breastfeeding. A clot roughly the size of a 50 pence coin (about the size of a large grape) is within the range of normal in the first 24 hours, though you should inform your midwife of any clots you pass so they can assess them.

Bleeding is typically heaviest in the first 24 hours after birth and during the first days. You will need maternity pads — not tampons or menstrual cups — throughout the entire lochia period. Maternity pads allow midwives to assess the amount and nature of the discharge and reduce the risk of introducing bacteria into the still-healing uterus.

Lochia Serosa: Days 5 to 10

Around day 4 or 5, the character of the lochia begins to change. It becomes pinkish, brownish, or orange-tinged — lighter in colour and thinner in consistency. This phase is called lochia serosa. The reduction in bright red blood reflects the fact that active bleeding from the uterine wall is decreasing, though shedding of tissue and fluid continues.

Flow is lighter during this phase. Many women move to lighter maternity pads or thick sanitary towels. Occasional pinkish spotting is normal. If the discharge returns to bright red at any point during this phase — particularly after a period of activity — this is a signal that you may have been doing too much. Increase rest and contact your midwife if it does not settle.

Lochia Alba: Day 10 to Up to 6 Weeks

The final phase of lochia is called lochia alba. The discharge becomes yellowish-white or creamy in appearance. It is light in volume — more of a discharge than a bleed — and may continue for up to 6 weeks postpartum, though for many women it resolves earlier.

Lochia alba consists mainly of white blood cells and mucus as the uterus completes its healing process. It does not have a significant odour. A mild, fresh smell is within the range of normal — a foul or offensive odour is not, and is a potential sign of infection requiring assessment.

Activity and Lochia: The Feedback Signal

One of the most useful things to understand about lochia is that it responds to activity. Overdoing things physically — whether that means being on your feet for too long, carrying heavy items, or returning to strenuous exercise too early — often results in a return of brighter, heavier bleeding.

This is not coincidence. The uterus is still healing and contracting. Increased physical activity increases blood flow and can disturb the healing wound at the placental site. If you notice your lochia becoming heavier or returning to a brighter red after a period of activity, this is your body's signal to slow down. Rest, lie down, and see whether the bleeding settles within a few hours.

Persistent return to heavy or bright red bleeding after resting is worth reporting to your midwife. It is a pattern that deserves assessment, particularly if it happens repeatedly.

Breastfeeding and Lochia

Breastfeeding affects lochia in a way that many women are not warned about in advance. During a breastfeed, the hormone oxytocin is released. Oxytocin causes the uterus to contract — you may feel cramping or tightening during feeds, especially in the early days. These are called afterpains and are usually stronger after a second or subsequent birth.

The contractions prompted by oxytocin during breastfeeding are helpful: they assist the uterus in shrinking back to its pre-pregnancy size more efficiently. However, they can also cause a temporary surge in the amount of lochia during or immediately after a feed.

Noticing heavier bleeding during or after breastfeeding in the first week is therefore normal and expected. It is not a sign that something is wrong. If the increased flow persists beyond the feed rather than settling, or if the volume is alarming, contact your midwife for reassurance.

What Is Not Normal: Warning Signs to Act On

Most lochia follows the pattern described above and resolves without complication. However, postpartum haemorrhage (PPH) — abnormal or excessive bleeding after birth — is the leading cause of maternal death worldwide according to WHO data, and it is essential to know the warning signs that require urgent medical attention.

Contact your midwife, call 999 (UK), or go to your nearest maternity unit immediately if:

• You are soaking through one maternity pad per hour or more for two or more hours in a row
• You pass a clot larger than a golf ball, or multiple large clots
• You feel dizzy, faint, confused, or unusually weak alongside heavy bleeding
• You have a rapid heartbeat, shortness of breath, or feel clammy
• Your lochia has a foul or offensive smell and you develop a fever of 38°C or higher — these are signs of postpartum infection (endometritis)
• Your bleeding seems to have stopped and then suddenly returns as heavy red bleeding well after the first two weeks without an obvious activity trigger

Postpartum haemorrhage can occur within the first 24 hours (primary PPH) or between 24 hours and 12 weeks after birth (secondary PPH). Secondary PPH is often caused by retained placental tissue or infection and requires prompt assessment. Do not dismiss heavy bleeding at any point in the postnatal period as "just lochia".

Using Maternity Pads Correctly

Throughout the lochia period, use maternity pads rather than tampons, menstrual cups, or period underwear with hidden absorbency. The reason is twofold: tampons and cups introduce a risk of infection into a healing uterus, and they prevent you (and your midwife) from accurately assessing the volume and character of the discharge.

Change pads regularly — every 2–4 hours in the heavy phase — both for comfort and hygiene. After using the toilet, wipe front to back, and wash hands thoroughly. Avoid perfumed pads, as fragrances can irritate sensitive healing tissue.

If you notice that you are consistently saturating pads very quickly, or that large clots are present on every pad change, raise this with your midwife. Do not assume it is normal simply because bleeding after birth is expected.

When Lochia Stops vs When Periods Return

Lochia typically resolves within 4 to 6 weeks of birth. However, some women notice a small episode of spotting at around 10–14 days — this can coincide with the time when the scab over the placental attachment site separates, similar in principle to a scab falling off a skin wound. This is usually brief and not a cause for concern, but is worth mentioning to your midwife if you are unsure.

The return of menstrual periods after lochia has finished varies considerably. For women who are formula feeding or who are not breastfeeding, periods can return as early as 6 weeks postpartum. For those who are exclusively breastfeeding, the hormone prolactin suppresses ovulation, and periods may not return for 6 months or more — sometimes not until breastfeeding is reduced or stopped. This is known as lactational amenorrhoea.

It is important to note that lactational amenorrhoea is not a reliable contraceptive method unless strict criteria are met (baby under 6 months, exclusively breastfeeding, and no return of periods). Discuss contraception with your GP or midwife before your period returns if you do not wish to conceive again immediately — ovulation can occur before the first period, meaning pregnancy is possible before periods resume.

The Difference Between Lochia Returning and a Period

Sometimes it can be difficult to tell whether spotting or bleeding after the lochia has apparently resolved represents lochia returning, a period, or something else. Generally speaking:

• Lochia returning within the first 6 weeks and settling after rest is likely to be lochia
• A heavier bleed returning after 6 weeks, particularly with the cyclic pattern typical of a period, is more likely to be a first period
• Any heavy bleeding with accompanying pain, fever, or unpleasant odour at any time should be assessed by a healthcare provider

If you are unsure, contact your midwife (if within 6–8 weeks of birth) or your GP. There is no such thing as an unnecessary call about postpartum bleeding.

After a Caesarean Section

Lochia occurs after a caesarean section just as it does after a vaginal birth. The uterus sheds its lining regardless of the delivery route. Some women are surprised by this — they assume that because the baby was not born vaginally, there will not be postpartum bleeding. This is not the case.

Lochia after a caesarean section may sometimes be slightly lighter in the first few days compared to vaginal birth, as the surgeon clears some uterine content during the procedure. However, the same three phases of lochia apply, and the same warning signs are relevant.

Women who have had a caesarean section also face the added complexity of a surgical wound. If you notice heavy bleeding alongside wound pain, swelling, or leaking from the wound site, seek immediate assessment.

Frequently Asked Questions

Is it normal to pass clots in the first week?

Small clots — up to the size of a 50 pence coin or a large grape — are within the range of normal in the first 24–48 hours. Clots form when blood pools when you lie down and then is expelled when you stand up. A single large clot (golf-ball size or larger) is always worth reporting to your midwife. Multiple large clots or clots accompanied by very heavy flow require urgent assessment.

Can I have a bath or shower while experiencing lochia?

Yes. Bathing and showering are safe throughout the lochia period. A bath may cause the lochia to look heavier temporarily because blood that has pooled in the vagina is washed out. This is not a sign of increased bleeding. Use plain, unscented products and avoid sitting in water for very long periods in the early days.

My lochia had almost stopped and now it has come back. Is this normal?

A return of pinkish or light red lochia after a period of apparently settling is common and usually reflects increased activity. Rest and monitor. If it returns to heavy bright red bleeding, passes large clots, or is accompanied by any other symptoms, contact your midwife or GP.

Does lochia have a smell?

Lochia has a faint, distinctive smell described variously as earthy or stale — similar to a heavy period. A foul, fishy, or very strong unpleasant odour is not normal and is a potential sign of uterine infection. A high temperature alongside a foul odour requires prompt medical attention.

When should I see a doctor about lochia?

Contact your midwife or GP if: bleeding is becoming heavier rather than lighter after the first few days; you have passed large clots; the smell is unpleasant; you develop a fever; you feel unwell. Go to your hospital maternity unit or call 999 if bleeding is very heavy, you feel faint, or you are concerned at any point.

Can I use a menstrual cup once lochia has finished?

Once lochia has fully resolved and your cervix has closed (typically by 4–6 weeks), a menstrual cup can be used when periods return. However, it is advisable to discuss this with your GP if you have had any perineal trauma, as scar tissue or pelvic floor changes may affect insertion and comfort.

Key Takeaways

• Lochia progresses through three phases: bright red (days 1–4), pinkish-brown (days 5–10), and yellowish-white (up to 6 weeks) — each phase is a normal part of uterine recovery.
• Clots up to the size of a 50 pence coin can be normal in the first 24–48 hours; larger or multiple clots should be reported to your midwife.
• Breastfeeding triggers uterine contractions via oxytocin, which can cause a temporary increase in lochia during feeds — this is expected and not alarming.
• Activity worsening lochia is a signal to rest; if heavier bleeding does not settle after a period of rest, contact your midwife.
• Soaking more than one pad per hour, passing golf-ball-sized clots, foul odour with fever, or feeling faint require urgent medical assessment — these are warning signs of haemorrhage or infection.
• The return of periods after lochia varies widely: from 6 weeks in formula-feeding mothers to 6 months or longer in those exclusively breastfeeding.
