Postpartum bleeding, called lochia, typically lasts about six weeks. Some people have traces of it for up to eight weeks. The bleeding changes significantly over that time, shifting in color, volume, and consistency as your body heals from delivery.
Why Postpartum Bleeding Happens
When the placenta detaches from your uterine wall during delivery, it leaves behind an open wound roughly the size of a dinner plate. Your uterus immediately begins contracting to shrink back to its pre-pregnancy size, a process called involution. Those contractions compress the blood vessels at the placental site and reduce blood flow to the area, which is your body’s primary way of controlling the bleeding. Over the following weeks, the wound gradually closes and new tissue forms over the site.
This is why you’ll feel cramping in the days after birth, especially while breastfeeding. Nursing triggers the release of oxytocin, which stimulates uterine contractions. Those contractions can be uncomfortable, but they’re actively helping your uterus shrink and the bleeding slow down.
What to Expect Week by Week
Lochia moves through three distinct stages, and tracking the color is the easiest way to gauge where you are in the process.
In the first few days after delivery, lochia is bright red and heavy, similar to a very heavy period. You may pass small blood clots. This is the heaviest phase, and it’s normal to soak through a maternity pad every few hours. By the end of the first week, the flow typically starts to ease.
Over the next one to two weeks, the discharge shifts to a pinkish or brownish color and becomes lighter. It’s mostly made up of old blood, fluid, and white blood cells as the uterine lining continues to shed.
From roughly week three through week six, lochia turns yellowish or creamy white. The volume drops significantly, and many people describe it as light spotting or a thin discharge. Some days you may barely notice it, while other days (particularly after physical activity) it may pick up slightly. This on-and-off pattern near the end is normal.
Vaginal Birth vs. Cesarean Section
Lochia lasts about the same amount of time regardless of how you delivered. A cesarean birth doesn’t skip the process, because the bleeding comes from the placental wound site inside the uterus, not from the vaginal canal itself. Some people who had a cesarean notice slightly less lochia in the first day or two, since some blood and fluid is cleared during surgery, but the overall timeline stays around six weeks.
How Breastfeeding Affects Bleeding
Breastfeeding can make lochia heavier in the short term. Each time your baby latches, your body releases oxytocin, which triggers uterine contractions. You may notice a temporary gush of blood during or right after nursing sessions, especially in the first week or two. This is normal and actually beneficial. Those extra contractions help the uterus shrink faster, which can shorten the overall duration of bleeding for some people.
Breastfeeding also has a major effect on when your period returns. If you’re exclusively breastfeeding, your regular cycle may not come back for months, sometimes not until you wean. If you’re formula feeding, your period can return as early as six to eight weeks postpartum. This matters because it can be hard to tell whether new bleeding at the six-to-eight-week mark is the tail end of lochia or an actual period. If the bleeding starts as brownish spotting and gradually increases to a flow with typical period symptoms, it’s more likely menstruation. Keep in mind that ovulation can happen before your first period returns, so pregnancy is possible even if you haven’t had a cycle yet.
Warning Signs of Excessive Bleeding
Some amount of heavy bleeding in the first days is expected, but certain patterns signal a problem. Contact your healthcare provider if you experience any of the following:
- Soaking more than one pad every one to two hours. A single heavy pad in an hour, especially if it continues, suggests bleeding beyond the normal range.
- Passing large blood clots. Small clots in the first few days are common, but clots larger than a golf ball or a sudden increase in clot size needs attention.
- A sudden return to bright red, heavy bleeding after it had already started to taper off, particularly if it happens after the first two weeks.
- Foul-smelling discharge. Lochia has a mild, musty smell. A strong or unpleasant odor can indicate a uterine infection.
- Fever, chills, or feeling increasingly unwell. These alongside changes in your bleeding may point to infection.
Postpartum hemorrhage, defined as blood loss of 500 milliliters or more, most often occurs within the first 24 hours after delivery. But it can happen up to 12 weeks later. Late postpartum hemorrhage sometimes results from a piece of retained placental tissue or from the uterus not shrinking properly, a condition called subinvolution. In subinvolution, the blood vessels at the placental site don’t close down as they should, allowing bleeding to continue or restart.
Pads Only for Six Weeks
Use maternity pads or regular sanitary pads for the entire duration of lochia. Tampons, menstrual cups, and other internal products should be avoided until after your six-week postnatal checkup. The wound where the placenta was attached is still healing during this time, and any tears or incisions from delivery also need to close. Inserting anything into the vagina before that healing is complete raises the risk of infection.
Physical activity can temporarily increase your flow, so if you notice heavier bleeding after being on your feet for a while, it’s a signal to slow down. Gravity also plays a role: you may notice a gush of blood when you stand up after sitting or lying down for a long time, which is just pooled blood releasing. It’s not a sign of a new problem unless the volume is consistently heavy.
