Info On Placenta Praevia

Here is some info on it:
What is placenta previa?
If you have placenta previa, it means that your placenta is lying unusually low in your uterus, next to or covering your cervix. The placenta is the pancake-shaped organ — normally located near the top of the uterus — that supplies your baby with nutrients through the umbilical cord.

Placenta previa is not usually a problem early in pregnancy. But if it persists into later pregnancy, it can cause bleeding, which may require you to deliver early and can lead to other complications. If you have placenta previa when it's time to deliver your baby, you'll need to have a c-section.

If the placenta covers the cervix completely, it's called a complete or total previa. If it's right on the border of the cervix, it's called a marginal previa. (You may also hear the term "partial previa," which refers to a placenta that covers part of the cervical opening once the cervix starts to dilate.) If the edge of the placenta is within 2 centimeters of the cervix but not bordering it, it's called a low-lying placenta. The location of your placenta will be checked during your midpregnancy ultrasound exam.
