Patient: One day ny bf and I had sex and in the middle of it I had a really bad cramp almost like a mensrual cramp but it had more pressure with a sharpness to it we looked up so many things online and there could be a miscarriage or a disease . I took 2 pregnancy tests both came back negative. If it were a miscarriage though we thought that the reason it came baxk negative was cuz of that. Please help.-tasia.
