So... I had my period from Jan. 1 to Jan. 5 . Had unprotected sex on the 13th, we didnt use a condom and I know he didnt pull out... I started my "period" again on the 22nd.... barely bleeding but HORRIBLE cramps, probably the worst I've ever had. I've been nauseous and not able to eat much because just thinking about the smell or texture of food is making me sick... I've taken 2 tests and both have been negative. I'm not sure what exactly is happening... I have had a failed pregnancy and the only thing I can think about right now is having to go through that heartache again.
