My last period cycle started on 12/23 and ended 1/2. I had sex during my fertile window (unprotected) and had light bleeding 1/16-1/8. My next period was due 1/21 but it was really late. I got it yesterday (2/1), all pregnancy tests came out negative but I’ve had pregnancy like systems for two weeks before. Can I still be pregnant even though I just got my period? I just want to be sure that I’m not pregnant.
