About 2 weeks ago, my boyfriend and I had unprotected sex. He claims he did not ejaculate inside of me and that he was completely dry; however, he did ejaculate moments before we had sex, but it dried. Ever since, I've been completely worried that I may be pregnant. It appears my period is late, and I've been experiencing pain in my neck and stomach since then along with nausea but no vomit. Last night, I believe I found brown discharge in my underwear, and I'm not sure what to think. If my parents found out I had sex, I'd be in a great amount of trouble, and my boyfriend and I agreed not to have sex again until we're positive we're ready. Should I be worried that I'm pregnant? I'm 14 and I'm really scared.
