I am 15 years old and will be a sophmore next month when school starts back up. My boyfriend is 17 and will be a senior this year. We live in different towns and go to different schools. We have been dating for going on 4 months now and we love eachother very much. All of our family and friends have even said that this is "the one". He's already given me a trust ring and will soon be giving me his class ring as a promise ring. We are crazy about eachother and lately we've been talking about physical things. At first when we started talking about it, we had set bounderies. We had both decided that we would just stick with the smaller things and save sex for marriage or until we were moved in together next year when I'm 17. However, I spent this past weekend at his house and two days ago when we came back to my house when he took me home, we had the house to ourselves all evening because my mom was away camping for the week. Up until then, we had done a great job of having control. We had set bounderies and had stuck by it. Yes we had both wanted to have sex, but we would always stop before it happened. However, when we got back to my house, things began to happen and the more intense it got, the more we wanted to go all the way. So we stopped and we talked about it for what seemed like forever. We decided that we were both okay with going ahead with it and he said that if anything happened, he would stay and step up and deal with the responsibility. We had sex two days ago, three times, and he didn't use a condom because we didn't have any at the time because we didn't expect anything to happen. He pulled out and I figured that I had just gotten off of my period the day before, I would be safe...But now, after doing a lot more research on the internet and reading about other women and teen girls' stories, I know for a fact neither one of those works and that right after your period is the worst time to have sex. I have been on birth control for the past 2 or 3 years but ran out back in March and have not gotten a chance to go back to the doctor since then, to get them refilled. I go back in about two weeks and will be back on it then and now I have condoms. What I'm worried about though is that I may be pregnant already...What do I do? What are my chances that I could be pregnant? I'm 15 and will be 16 when my baby is born, if I AM pregnant that is...I'm the one daughter of my mom's that has not entirely screwed up their life and I don't want to disappoint her or my family/friends or my boyfriend's family or friends...We love eachother dearly and know we are staying together and if something did or DOES happen, we are both going to take full responsibility. But what do I do? I have no idea how the whole menstral cycle works because they did not do a good job of teaching us that in school, so I am not sure when the safest time to have sex is really...Any advice about anything I've talked about? My period is messed up usually so I'm completely confused. I go into the doctor July 16th and if my period is the regular normal 28 days this month, my next one should be July 22nd or 23rd. Advice please???!!!
