Me and my boyfriend were making out with both of us only wearing underwear. I am on my period and was wearing a pad. I didn't take my underwear off but he ejaculated onto his stomache and the sperm made contact with the top part of my underwear, I've checked and it doesn't seem to have seeped down into the vaginal area and definitely not into the canal. Once I was home I had taken my underwear off, changed my underwear and my pad, and washed myself in the vaginal area. I am still bleeding but am not sure if I could've gotten pregnant. I would really appreciate it if someone responded immediately, I was never planning on having sex and definitely not planning on becoming pregnant. I am not on birth control and he was not wearing a condom, we both weren't planning on having sex or even removing our underwear. PLEASE RESPOND ASAP.
