A gynae told me the same thing. But didn’t advise me on it. My fixed gynae didn’t say anything about it at all throughout my pregnancy. I had a planned csect at week37, partly because I was already 1cm dilated. Not sure if it was cause by the low lying placenta.
In my 13th week check up, Dr said I've a low-lying placenta. Said that if by 20th week it doesn't shift, she will recommend reduced movement for me. Meaning normal walking but no brisk walking, no exercises.
