Hello. I have been with my boyfriend for going on 3 years we have been trying for a baby for a year. I have taken 3 test 1 positive very lightly and other 2 neg im spoce to take another in a week. I Anyway my question is im having abdominal pain after we had sex i showered to see if it would help and it didn't layed in bed for a bit and ended up running to the bathroom wasn't so easy and throwing up. He made me a bed on the couch and i was wondering if a heating pad is a good idea it feels good but idk since idk if im pregnant or not also what could this be?
