I lost my virginity on January 6,2017 and been paranoid since. We did not use protection but he also said he didn't cm in me. I took a pregnancy test when I woke up on January 21 it was negative. Later that day I've gotten my period so it lasted January 21- January 23. Usually my period last about 3 days. But the flow was just different than what I'm used too. January 30th I took another pregnancy test in the morning it was negative. I'm tired a lot now... is it possible that I'm pregnant? I will never have unprotected sex again!
