S.E.
I had placenta previa in the first 1/2 of my pregnancy but it moved off to the side before delivery. Did the OB say that you had placenta previa or is this something you are worried could happen?
If you have placenta previa they will watch you very close and you will have a planned c-section. You can not go through labor and delivery if you have full blown placenta previa. I think you should discuss this over with you doctor some more.
Best of luck,
S.
