Okay makes me feel a lot better, thank you!
Mine had moved by 36 wks and I had a vaginal delivery with no problems.
oops, sorry, the placenta moves out of the way, not the cervix.
I agree, 95% of the time, the cervix moves out of the way. If it doesn't move, and becomes a serious problem, you will be well aware of it and a life threatening condition for you (loss of blood) won't happen quickly where you can't make decisions in time to save yourself and your baby, if the baby is far enough along.
Watch for bleeding, and if there isn't any or it's light spotting, you're fine.
I had the same thing. And it moved by the time I had another sonogram.
