Well, I'm scared. Hopefully someone can help me!
About a week ago, my boyfriend and I had sex for the first time. I lost my virginity to him. We've had intercourse twice since then, and all three times were unprotected, although he was able to withdraw before ejaculating inside me. He's eighteen and I'm seventeen.
The problem is that now my boyfriend and I are scared to death that I'm pregnant. We know that the odds are low, but until I can take a pregnancy test, we just want to know what exactly the probability is.
I know that I wasn't ovulating any of the times we had sex, he was able to pull out well before ejaculating all three times, and there was little, if any pre-ejaculate. I realize that pre-ejaculate itself can contain plenty of sperm, particularly if a man has ejaculated before that day, which my boyfriend did, but he's fairly certain that he urinated in between these ejaculations, which I understand helps rid him of excess sperm.
The only reason we're uneasy about the threat of a potential pregnancy is that my period is at least a day late, and I don't feel it coming on like I often do when I'm about to start.
I realize that stress can make your period late, and I am certainly stressed! I've never really kept track of it before, so I don't know if this is 100% normal or not.
Thank you!
