I was on antibiotics at the end of last month, then started my birth control pack the first of the month. I was on the first day, and had unprotected sex. He did use the withdraw method, but he was also drunk. It's the third day on my sugar pills with no period. I haven't had craps, bleeding/spotting, no urge to pee, but I have been tired(but I think that's just due to being tired from life). I'm just worried and I'm prolly freaking myself out. Any ideas if I am or not? I'm just trying to relieve myself of this worry.
