My boyfriend and I were doing whatever, and one thing led to another, and he ended up going inside me. This was a first for me. I wouldn't say we really had sex because he thrusted a few times, and then I told him to stop, even though I really didn't want him to. I'm on the pill, but I'm not the greatest with it. I occasionally take it about 3-4 hours late (maybe like once every 2 weeks). He wasn't wearing a condom, but he also never came. Then once I became freaked out, he went and bought me Plan B. But then I read today that Plan B isn't effective for women with high BMI's, and I'm pretty overweight. So is there any chance of me being pregnant? I don't think so, but once you read every article about the slight ineffectiveness of Plan B and birth control, and the chances of pregnancy by pre cum then it's pretty easy to get freaked out. Let me know if him and I are insane. Thanks!
