I had unprotected sex with my girlfriend 6-7 days ago, i'm sure I didn't ejaculate inside her, coz I completely ejaculated on her hands, but 1 day after our intercourse, she had some vaginal bleeding. She was a virgin hence it was our first time so I thought it was normal and we ignored it. But now she is complaining me about little bit pain in her lower abdomen, she feels like peeing several times a day, and today she is feeling like constipation. I'm scared if she's pregnant. please help me.
