What Is Lochia? Stages, Duration, and Warning Signs

Lochia is the vaginal discharge your body produces after giving birth. It’s a mix of blood, mucus, and uterine tissue that flows for several weeks as your uterus clears out everything it built up during pregnancy. Despite the word “pregnancy” in the search, lochia is technically a postpartum process, not something that happens while you’re still pregnant.

During pregnancy, your uterus expands dramatically and develops a thick lining of extra blood and tissue to support the growing baby. Once the baby and placenta are delivered, your body no longer needs any of that. Lochia is the cleanup process: your uterus sheds the leftover blood, fluid, and tissue so it can return to its pre-pregnancy state. Think of it as a prolonged, changing discharge that signals your uterus is healing.

The Three Stages of Lochia

Lochia isn’t the same from start to finish. It changes in color, volume, and texture over the course of several weeks, and those changes follow a fairly predictable pattern broken into three stages.

Lochia rubra is the first stage, lasting roughly the first three to four days after delivery. This is the heaviest flow. It’s bright red and mostly composed of blood, along with small clots and fragments of uterine lining. It can feel similar to a very heavy period, and you may notice it increases when you stand up after lying down or when you breastfeed.

Lochia serosa follows, typically from around day four through day ten. The color shifts from red to a pinkish or brownish tone as the blood content decreases and the discharge becomes more watery. It contains less fresh blood and more of the fluid and old tissue your uterus is still clearing.

Lochia alba is the final stage, which can stretch from about day ten through four to six weeks postpartum. By this point, the discharge is yellowish-white or cream-colored and much lighter in volume. It’s mostly made up of white blood cells, mucus, and residual cellular material as the uterine lining finishes its repair.

How Long Lochia Lasts

Most people experience lochia for four to six weeks after delivery, though the heavy bleeding phase is concentrated in the first week. The transition from one stage to the next is gradual, not a sudden switch. Some people notice the discharge tapering off by three weeks, while others have light spotting that lingers closer to six weeks. Both timelines are normal.

Lochia occurs whether you deliver vaginally or by cesarean section. A C-section may involve less initial discharge because the surgeon removes some of the uterine contents during the procedure, but the uterus still needs to shed its remaining lining. You can expect a similar overall timeline regardless of delivery method.

Why Breastfeeding Affects Your Flow

If you breastfeed or pump, you’ll likely notice that your lochia increases during or right after a feeding session. This happens because nursing triggers the release of oxytocin, a hormone that causes your uterus to contract. Those contractions, sometimes called “afterpains,” squeeze the uterus and push out more discharge. They can feel like mild to moderate menstrual cramps and are usually most noticeable in the first few days after birth.

The upside is that breastfeeding actually speeds up the overall healing process. Because oxytocin keeps your uterus contracting, it shrinks back to its pre-pregnancy size faster. So while you may see heavier flow in the moment, breastfeeding generally helps your body finish the job sooner.

Managing Lochia Day to Day

For the first several weeks postpartum, use pads rather than tampons to absorb the discharge. Your cervix is still closing and your uterine lining is raw and healing, which makes introducing anything into the vaginal canal a risk for infection. Most providers recommend avoiding tampons, menstrual cups, and similar internal products for at least the first six weeks, or until you’ve been cleared at your postpartum checkup.

In the early days, you may go through heavy-duty maternity pads quickly. As the flow lightens through the serosa and alba stages, you can switch to regular pads or pantyliners. Wearing dark, comfortable underwear and keeping extra pads nearby (especially at night) makes the first week or two more manageable.

Normal lochia has a mild, stale blood smell, similar to a period. It shouldn’t smell strongly foul or rotten. A musty or metallic scent in the early days is expected, but a sharp, unpleasant odor can be a sign of uterine infection.

Signs That Something Is Wrong

Some postpartum bleeding is heavy, and that’s normal in the first few days. But there are thresholds that signal a problem. If you’re soaking through a full-size pad in 60 minutes, that’s considered heavy lochia. If you’re saturating a pad in 15 minutes, that’s classified as excessive and could indicate postpartum hemorrhage.

Other warning signs to watch for include:

  • Large blood clots: Small clots in the first few days are common, but clots larger than a golf ball deserve attention.
  • Foul-smelling discharge: A strong, offensive odor can indicate endometritis, an infection of the uterine lining.
  • Return to bright red bleeding: If your lochia has already shifted to pink or brown and then turns bright red again, it may mean you’re overexerting yourself or that something else is going on.
  • Fever or chills: Combined with changes in lochia, these can point to infection.
  • No lochia at all: A sudden stop in discharge in the first week could mean a clot is blocking the cervix, preventing the uterus from draining properly.

Heavy bleeding in the first 24 hours after delivery is the most common window for postpartum hemorrhage, but it can happen up to 12 weeks later. If your bleeding pattern suddenly worsens after it had been improving, that’s worth getting evaluated promptly.

Lochia After a C-Section

If you had a cesarean delivery, your lochia experience will look mostly the same as after a vaginal birth, with a few differences. The initial volume tends to be slightly lower because the surgical team suctions and wipes the uterine cavity during the procedure. But your uterus still has lining to shed, so you’ll go through the same rubra, serosa, and alba progression over the following weeks.

One thing to be aware of: because you’re also recovering from abdominal surgery, it can be harder to distinguish between normal postpartum cramping (from uterine contractions) and pain from your incision. Both are expected, but pain that’s getting worse rather than better after the first few days, or pain accompanied by fever and foul-smelling lochia, is a reason to get checked.
