Hello. My girlfriend and I have never had sex but we have rubbed on each other while naked and there is a possibility that my pre-cum got on her. This was about a week or 2 ago. I never went inside of her. A couple of days ago, I was sticking my finger in her and it was turning her on. After about 5 minutes, I noticed some blood down there. She said that she did not feel any pain, and we thought that maybe I accidentally cut her a little bit with my finger. That scared us. Lately, her boobs seem bigger and sore and she also has a yeast infection. She also goes pee a lot. It is too early to take a pregnancy test and she isn't expecting her next period until later this month. Does it sound like she is pregnant or are we just scaring ourselves? Thank you for your comments.
