My last period was February 3-8. My period is a week late today. My boyfriend stuck his penis in me for only a couple seconds because I changed my mind. Other than that we’ve always used condoms. I’m worried that I’m pregnant, I’m always paranoid about this. I have started going to the gym, for about two weeks ( I read that exercise could delay period). My nipple was stinging while being played with, but I think that’s because of not wearing proper bra at gym. Also have watery discharge, and have been crying a lot. Should I be worried?
