So my bf and I had unprotected sex about 5 weeks ago. Last week I had my period, but it was really weird. It was lighter than normal and lasted only about two days with very little clotting than normal. Also I had bad cramps one morning but other than that I didn’t which is also very unusual. Normally I cramp pretty bad for three days. I still feel sick but I’ve taken three tests and they are all negative. My bf thinks I am pregnant even tho the three tests have come back negative. Any thoughts or suggestions?
