Me and my boyfriend had sex on June 3, 2014. While having sex, the condom broke but he did not ejaculate and we realized it pretty fast and replaced it. I have been on birth control for a year and a half but I am still very scared of being pregnant. I am on Apri combination pills and I take them at the same time every day and I don't miss any. We had sex 2 days after my period went off. Ever since then, my body has been bothering me. I think I have scared myself into pregnancy symptoms because it is all I think about and I have been looking at a lot online. I am constipated, have chest pains, and abdominal pains. I have also been very gassy and burping a lot. Every time something happens, I think it is a pregnancy symptom. My period is not due until next week but I feel like I have stressed so much that it will be late. I'm only 18 and I'm really scared. Please help.
