Me and my girlfriend were dry humping two weeks ago; we were both on our underwear, and I never ejaculated, however i did noticed drops of pre-cum on my boxers. I was dry humping exactly in the vagina's entrance, and i was very nervous by those little pre-cum drops entering her vagina. It's been 4-5 days since her period should have came, and we are both very nervous of pregnancy happening. She feels like her period it's just around the corner, however nothing, we are very worried. Are there any chances that she is pregnant? (It's the missing period what's keeping us very worried). I know dry humping shouldn't result in pregnancy, however I am worried that we just had very very bad luck.
