So I'm probably overreacting a bit, but now I'm getting worried. I had sex with someone back in April, the condom wasn't on for like, a minute or two at most, and he didn't finish during that time (or even inside me at all). I had periods in May and June, but did not get one in July. Less than 24 hours after the sex happened I took a plan b, but I now know I'm over the weight limit. I was on hormonal birth control (seasonique) for almost two years, but got off of it at some time in March. I've also had times since then that I've drank excessively, but other than a hangover nothing else happened. I know I'm probably worried for nothing but could I actually be pregnant? I haven't had any other symptoms, literally just the absent period for one month.
