Lochia rubra is the first stage of postpartum bleeding that begins immediately after giving birth. It looks and feels like a heavy period, with dark or bright red blood that can include small clots. This discharge is your body’s way of clearing out the extra blood, tissue, and fluid that built up during pregnancy to support your baby. It happens whether you had a vaginal delivery or a cesarean section.
Why Postpartum Bleeding Happens
During pregnancy, your uterus expands dramatically and builds up a thick lining of extra blood vessels and tissue to nourish the growing fetus. Once your baby and placenta are delivered, your body no longer needs any of that. Lochia is essentially your uterus cleaning house, shedding months’ worth of accumulated material so it can return to its pre-pregnancy size.
The discharge is a mix of blood, amniotic fluid, leftover fetal membranes, cervical mucus, bacteria, and tissue from the uterine lining. In the rubra stage, blood is the dominant component, which is why the color is distinctly red. As healing progresses over the coming weeks, the composition shifts and the color changes accordingly.
What Lochia Rubra Looks and Feels Like
Expect dark or bright red bleeding similar to or heavier than your heaviest menstrual period. Small blood clots are normal during this stage, as long as they’re smaller than a quarter. The flow is typically heaviest in the first few days after delivery and gradually tapers. You may notice a temporary increase in flow when you stand up after lying down, breastfeed, or move around more than usual. Breastfeeding can cause a noticeable gush because nursing triggers your uterus to contract, which helps it shrink but also pushes out more blood in the moment.
The discharge may have a mild, slightly metallic smell similar to menstrual blood. A foul or unusually strong odor is not part of normal healing.
How Long It Lasts
Lochia rubra typically lasts about three to four days after delivery, though it can extend up to a week for some people. As the bleeding slows and the uterine lining continues to heal, the discharge transitions into the next stage, called lochia serosa. This stage is pinkish-brown or watery pink, much lighter than rubra, and lasts roughly until two to three weeks postpartum. The final stage, lochia alba, is a yellowish-white or cream-colored discharge that can continue for up to six weeks after birth.
The overall progression from red to pink to white is a reliable sign that your uterus is healing on schedule. If your discharge returns to bright red after it had already started to lighten, that can be a signal you’re overdoing it physically and need more rest.
Managing the Bleeding
Postpartum pads are the standard choice for managing lochia rubra. These pads are larger and more absorbent than regular menstrual pads, designed specifically for the heavier flow of the first few days. You’ll likely need to change them frequently, especially in the first 24 to 48 hours.
Tampons and menstrual cups should not be used during any stage of lochia. After delivery, you may have tears, stitches, or cuts in or around your vagina. Inserting anything into the vaginal canal during this healing period raises the risk of infection. Stick with pads until your postpartum checkup confirms you’ve fully healed.
Many hospitals send you home with mesh underwear and oversized pads. Some people also layer a regular pad on top of a postpartum pad or use disposable underpads on their bed for extra protection, especially at night when you may not notice a heavier flow.
Signs That Something Is Wrong
While lochia rubra itself is completely normal, certain changes in the bleeding pattern can signal a problem that needs immediate attention. The most important one to know is postpartum hemorrhage, which is bleeding that soaks through two pads in an hour for more than one to two hours. Passing large blood clots (bigger than a quarter, and especially golf-ball sized or larger) also falls outside the normal range.
Other warning signs that warrant a call to your provider right away include:
- Foul-smelling discharge, which can indicate an infection in the uterus
- Fever and chills, another sign of possible infection
- Feeling faint, dizzy, or weak, which may point to excessive blood loss
- Pale or clammy skin paired with a rapid heart rate
- Abdominal pain or tenderness that feels different from normal postpartum cramping
- Confusion or difficulty thinking clearly
Postpartum hemorrhage most often happens within the first 24 hours after delivery, but it can occur up to 12 weeks later. Knowing the pad-saturation threshold (two pads per hour for one to two hours) gives you a concrete way to gauge whether your bleeding has crossed from heavy-but-normal into something that needs medical evaluation.
Lochia After a Cesarean Birth
If you delivered by cesarean section, you will still experience lochia. Some of the blood and tissue is removed during surgery, so the overall volume may be slightly less than after a vaginal delivery. But the same progression from rubra to serosa to alba applies, and the same warning signs hold true. The main difference is that you’re also recovering from abdominal surgery, so any increase in bleeding paired with incision-site changes (redness, swelling, discharge from the wound) should be reported to your provider.
