Okay, so I am on the pill. and about a 3 and half weeks ago I hooked with this guy. We did not use a condom, he did pull out however. Im scared because I havent had my period yet, but theres been a lot of white discharge this week. also, the week we did it, i forgot to take my pill until like 6 or 7 hours after i normally take it. and that was 3 or 4 days before having sex. PLEASE someone help me. Im freaking out. My periods are never that regular. But i feel like i should have already started. Also, in the last month I have taken up running every single day, which is something new for my body. I was told that could mess with my period? is that true? i dont want to be pregnant. somebody pleeeeease help me out.
