Me and my girlfriend are underage, 3 days ago we had sex and used a condom. From her face it hurt quite a lot and so we didnt try to go deep. I love her and didn't want to force it in hard. She ate a lot that day (the whole day, not only after the intercourse), more than usual. Her stomach has been hurting for the past 3 days (about 9 hours after we had sex it started hurting). The pain is slowly going away (she almost doesnt feel it anymore) and today her belly seems to be bigger. It hurts when being pressed with hands. Her period starts in about 2 weeks. I'm scared and paranoid she might be pregnant. Any help? PLEASE?
