Placenta previa happens when the placenta partly or completely covers the cervix, which is the opening of the uterus. Your baby passes from the uterus into the cervix and through the birth canal during a vaginal delivery. Normally, the placenta attaches toward the top of the uterus, away from the cervix. Hereâs what happens with placenta previa: As your cervix opens during labor, it can cause blood vessels that connect the placenta to the uterus to tear. This can lead to bleeding and put both you and your baby at risk. Nearly all women who have this condition will have to have a C-section to keep this from happening.
