90% of the time it moves where it should. I had total placenta previa my second pregnancy. By 30 weeks it had moved up. Just listen to your doctor on the things you can't do and you'll be fine.
Thank you :) did you have to have c section still or not?
I had placenta previa with my current pregnancy. I found out at 15 weeks and mine moved up by 30 weeks. It's way more common for it to move up on its own than to not. If you experience any bleeding though you should call your dr right away.
