Okay so there's obviously a chance i could have gotten pregnant. I'm on the pill but after my placebo pills ended i didn't get my next pack for a week. And i had unprotected sex in that week, he came in me that week. I started my birth control a week later then usual. So I'm confused because I'm bleeding today. It's light pink on toilet paper, but it was long stringy red blood in the toilet. Would i get my period early because i started later then usual? On this pill pack my withdraw period isn't until like a week from now. I'm not on the placebo pills yet. I did just have sex last night so maybe I'm bleeding from sex??? I usually don't bleed from sex. I also have cramps, and acne. And i did take a birth control pill later then usual last night but if i do i usually have slight brown bleeding. What do you think it is??? My period?
