So I was supposed to get my period 5 days ago. I've never had sex. The only thing that could of possible happened is that my boyfriend might of gotten some precum on my underwear while we were fooling around. Even if that happened it wouldn't of been much at all. I feel like the chance of me being pregnant is small. But I'm still worried. The only thing differant is my boobs are slightly bigger but that's it. Usually my period is short but I'm 17 so I haven't paid attention to my cycle that closely especially cause i haven't ha sex. I've been sorta stressed because basketball had recently started. I haven't gained or lost weight. I'm not in any medications. I'm worried why I haven't gotten it.
