I had a low lying placenta with DD1 and bleed all the way through my pregnancy. My sisters bestfriend's cousin had AF all the way through her pregnancy,Didn't even know she was pregnant until she went to the hospital with severe stomach and lion pain (lol, loin pain), lol a big suprise, lol. She had broken up with her partner 6 months previously and both had moved on. Personaly I never got how she didn't know I knew from when
I concieved, lol, ask my husband, he'll tell you I'm psychic, I just know my body.
