Okay after sex I have really bad lower abdomen pain to the point where I can't move and just super uncomfortable I've asked a couple of my friends about it and one of them said they did that a lot during first trimester of her pregnancy and the other one told me she did that when she miscarried first of all I haven't took a pregnancy test BC I'm only 3 days late on my period and I've miscarried before and yes I had pains but not like this I would really appreciate some advice please and thank you
