I was dating this guy in December and we had unprotected sex a lot. Even around my period. I had gotten pregnant and found out two days before he dumped me for his ex girlfriend. Then I miscarried. Then I got with my current boyfriend and we had protected sex with condoms except one night when we were drunk but he "pulled out" (this was a little over a month ago) then today I got what was my period but it was really light and it came out brown and light pink. (My period is usually heavy) could I be pregnant or just Paranoid?
