Thanks everyone!! I feel beter about it now
Mine was low but moved so don't worry too much
This is actually pretty common. My placenta was also almost right over my cervix and low, but moved up like trying's did, and no real problem's after that (well, no problems that had anything to do with a low placenta anyway). They will monitor it and if it stays low they will have you take the appropriate precautions.
Hi I had low lying placenta with my first son and it was actually covering some of my cervix but it moved up later. Good luck to you
