I'm currently 20 weeks and just found out that my placenta is low. (The baby is sleeping on it...) I understand that for some that it might eventually move up but have read scary things on the Internet if it eventually doesn't. Anyone with low placenta experience to share?

I had placenta previa too for my 1st pregnancy. After entering into 3rd trimester, it moved up itself. Some people will experience bleeding throughout the pregnancy due to the low placenta. If it didn't move up itself, normally gynae will perform c-section to prevent any complications e.g. bleeding non-stop during natural birth.
