Postpartum bleeding, called lochia, happens to every person who gives birth, whether vaginally or by cesarean section. It typically lasts four to six weeks and progresses through three distinct phases, shifting from heavy and bright red to a light, yellowish-white discharge. Understanding what each phase looks like helps you tell the difference between normal healing and something that needs attention.
The Three Phases of Postpartum Bleeding
Your body sheds the blood, tissue, and mucus that lined your uterus during pregnancy. This happens in a predictable pattern, though the exact timing varies from person to person.
Days 1 Through 4: Heavy, Bright Red Flow
The first phase starts immediately after delivery. The bleeding is bright red and heavy, similar to a heavy menstrual period. You may pass small clots, generally no larger than a small coin. In the first two to three days, it’s also possible to pass one or two larger clots (roughly the size of a tomato) or several smaller ones (about grape-sized) without it being cause for alarm. That said, any clots you pass are worth mentioning to your midwife or doctor, and showing them when possible.
Days 5 Through 10: Lighter, Pinkish-Brown Flow
During the second phase, the flow becomes noticeably lighter and thinner. The color shifts from bright red to pinkish or brownish. Heavy clotting typically stops, and the discharge takes on a more watery consistency. You may still pass very small clots, about the size of your pinky fingernail, once or twice during this window.
Weeks 2 Through 6: Light, Yellowish-White Discharge
The final phase is a yellowish-white or cream-colored discharge. It contains very few red blood cells and is mostly made up of white blood cells, mucus, and skin cells from the healing uterine lining. The volume is light, and for many people it tapers off gradually until it stops entirely around the six-week mark.
Why Breastfeeding Affects Your Bleeding
If you breastfeed or pump, you may notice cramping and a temporary increase in bleeding during or just after a feeding session. This happens because nursing triggers the release of oxytocin, a hormone that causes your uterus to contract. Those contractions squeeze the blood vessels at the site where the placenta was attached, which actually helps minimize bleeding over time by shrinking the uterus back to its pre-pregnancy size. The process can feel uncomfortable in the early days, but it’s a sign your body is recovering efficiently.
Physical Activity and Temporary Increases
You may notice that bleeding picks up or briefly returns to a brighter red after physical exertion, even something as simple as a longer walk or climbing stairs. This is normal and happens because activity stimulates uterine contractions. Think of it as your body’s signal to ease up. If the bleeding returns to its previous lighter pattern after you rest, there’s generally nothing to worry about. If it stays heavy or gets worse, that’s worth a call to your provider.
Vaginal Birth vs. Cesarean Section
Many people assume a cesarean delivery means less postpartum bleeding since some blood and tissue are removed during surgery. In practice, the overall blood loss is comparable between the two delivery methods. Both involve the same process of the uterus shedding its lining and healing the wound left by the placenta. After a cesarean, you can expect the same three-phase progression of lochia. The main difference is that recovery also involves healing from abdominal surgery, which can make it harder to gauge what’s normal since you’re managing incision pain at the same time.
Tampons and Infection Prevention
Use only pads (not tampons or menstrual cups) for the entire duration of postpartum bleeding. The site where the placenta detached from your uterine wall is essentially an open wound, and inserting anything into the vagina before it heals raises the risk of infection. The standard recommendation is to wait until after your six-week postnatal checkup before using internal products.
When Bleeding Signals a Problem
Passing large clots after the first 24 hours, or continuing to pass clots beyond the first few days, is a reason to contact your provider right away. The same goes for bleeding that suddenly gets much heavier after it had already started to lighten.
A foul-smelling discharge is one of the clearest signs of a uterine infection. Other symptoms include pain in the lower abdomen, fever (often appearing within one to three days after delivery), chills, rapid heart rate, and a general feeling of being unwell. Some infections produce only a low-grade fever with no other obvious symptoms, so even a mild but persistent fever is worth reporting. Retained fragments of the placenta are one common trigger for infection, and they can also cause prolonged or heavier-than-expected bleeding.
Postpartum hemorrhage, defined as a cumulative blood loss of one liter or more accompanied by signs like dizziness, rapid heartbeat, or feeling faint, is a medical emergency. It most often occurs within the first 24 hours but can happen later. Soaking through a pad in an hour or less, especially if it happens repeatedly, is a key warning sign that bleeding has crossed into dangerous territory.
