Hello doc, I had sex on 20th september and my last periods were from 1-6th september. We used condoms while having sex but at the last go, we did?t use it and he ejaculated on my stomach and somewhere maybe near my vagina (not inside). But within 2 mins I washed all of it. And,also I took ipill within 4/5 hours. This was the first time we had sex. I don?t want to get pregnant, can you please let me know if there are any chances of it?
