Will I definitely bleed with placenta previa?

Placenta previa (pluh-SEN-tuh PREH-vee-uh) occurs when a baby’s placenta partially or totally covers the mother’s cervix — the outlet for the uterus. Placenta previa can cause severe bleeding during pregnancy and delivery. If you have placenta previa, you might bleed throughout your pregnancy and during your delivery.

What is the most common complication of placenta previa?

The greatest risk of placenta previa is too much bleeding (hemorrhage). Bleeding often happens as the lower part of the uterus thins during the third trimester of pregnancy. This causes the area of the placenta over the cervix to bleed. The risk of bleeding is higher if a lot of the placenta covers the cervix.

How can I stop bleeding from placenta previa?

Providers recommend cesarean birth (c-section) for nearly all women with placenta previa to prevent severe bleeding.

How much do you bleed with placenta previa?

How early do you deliver with placenta previa?

Timing of delivery — As discussed above, planned cesarean birth of patients with stable (no bleeding or minimal bleeding) placenta previa should be accomplished at 36+0 to 37+6 weeks. (See ‘Timing of delivery’ above.)

Why does placenta previa cause postpartum hemorrhage?

After the placenta is delivered, these contractions help put pressure on the bleeding vessels in the area where the placenta was attached. If the uterus does not contract strongly enough, these blood vessels bleed freely. This is the most common cause of postpartum hemorrhage.

What are the risks of placenta previa?
