Alright my breasts are tender, I'm having severe cramping twinges throughout the day and I'm constipated(tmi I know) I had unprotected sex last Monday and also had a very short period last week that lasted Thursday to Friday. I also had sex two weeks before that very short period. I already took two pregnancy tests on the day I was originally supposedly start my period which was four days after the actual bleeding and they were both negative. Was it just too early to test or am I really not pregnant? I'm so confused and this cramping is really starting to scare me. Help please!
