Placenta previa is a complication during pregnancy in which the placenta in lying unusual in the lowest part of the uterus and covers the opening of the cervix completely or partly.
Three types of placenta previa:
The placenta covers the mouth of the uterus completely.
The placenta is extended to the edge of the cervix but doesn’t cover the opening.
The placenta covers only a portion of the cervix.
This complication only occurs in 1 out of 200 pregnancies and more common in women who smoke and use cocaine, had cesarean sections, got pregnant with twins or more, have children at an older age, large placenta and abnormally developed uterus. The primary symptom of placenta previa is the sudden bleeding of the vagina after 20 weeks of pregnancy. The bleeding will stop on it;s own but will start again weeks after.
Placenta Previa will correct itself during pregnancy but if it doesn’t happen there are still things that can be done to manage it. The treatment will be based on the amount of bleeding, the baby’s position and how much cervix is covered. Your doctor may recommend bed rest and frequent check-ups but vaginal exams are not recommended.
Placenta previa can be very dangerous to you and your baby so it’s best to consult your doctor if you have a vaginal bleeding.
