I have the same, my gynae confirmed at week 18 after I had 2 incidents of bleeding. I have been advised the same. No physical work. Max pelvic rest. Also to avoid intercourse.
1 thing from my personal experience, if you are constipated do not apply pressure during bowel movements, in my both bleeding incidents i made this mistake.
As the size of uterus grows, the placenta moves along with it and it finally gets settled around week 32. It is not threatening to you or baby. If it doesn’t move, only problem will be that you wont be able to give birth vaginally, and your gynae will advise you for C-sec.
Hope our placenta moves to right place, sending good vibes 🙂🙏🏼
