Alright so my period was last Thursday to Friday. Usually it lasts four days. Well I had unprotected sex two weeks before that and just recently this last Monday. Right now I'm experiencing bloating larger nipples abdominal pain and vaginal pressure. I've taken two pregnancy tests last Sunday which was when I was supposed to get my period and they were both negative. What could be causing all of this to happen? Could I be pregnant? I really hope so. My fiancé and I are trying to conceive.
