Hi. I'm a 17 year old girl. I've been taking ortho tri cyclin for a year and a half now. I haven't missed any of the pills the whole time since i've been on them. But I have a few questions. First off, I should have gotten my period two days ago, and it still hasn't come. I'm worried about it. On top of that, me and my boyfriend had sex today and the condom he was wearing slipped off and he came inside me. When I looked at it, it looked like a majority of the sperm didn't go in, because a lot of it was oozing out of my vagina. I'm very, very concerned about getting pregnant. I'm on the green pill right now, the off pill. This only contributes to my concern of pregnancy. If any women out there have any advice whatsoever at all, please, please let me know something. Thanks.
