hello. i have a question about cramping while pregnant. well i am only 5 weeks along, about two times a week i get lil cramps that make me stop and sit for a min, well last night i had sex for the first time since i got pregnant, i told my fiance i was feeling really good, but then it started gettting tight. i told him to stop and the 3 mins later i could not move. it got so bad i started crying and i could not move for 20 mins, it felt like my uterus was contracting. so i had my fiance bring me down stairs to take a shower and i started getting dizzy and fainty. i had to sit down, and then right after that i went up stairs and started getting better, this was after an hour. i had NO bleeding but it felt like evreything inside me was going to fall out. is this normal?
