I was told after my 18 week ultra sound that I have placenta previa. The placenta is over top of my cervix. It is possible over he next couple months it will move, it is possible that it may not move. If it doesn't move it can cause in rare cases the placenta to tear. In not so rare cases it can cause bleeding throughout the pregnancy. I would like to hear from woman who have experienced this and what they went through, what their doctors recommended, etc. ( I know if it doesn't move a c section is the only option,but I'm already scheduled for one and had one with my first son)
