Me and my girlfriend were carried away after drinking at a party and I was wearing a condom while foreplay and while she was giving me her hand I ejaculated inside the condom while my penis was in her hand, but after removing condom with my hand I touched her vagina with my fingers though I didn't touch any of the sperm I am getting scared if any of my sperm went inside her, I don't remember properly as we were high but was aware that sperm should not go inside her vagina. She took I-pill within 3 hours after this incident happened and this is on 5th of January. On the second day and third day after this incident happened she had brown discharge from vagina. Now it's the 4th day and I am getting scared if she is pregnant. She's 18 years old, her hymen didn't break for sure. She had her last periods on 28th Dec. Can you please help me out, I don't want her to get pregnant at any case .I would like to hear form a gynecologist.
