I am a 19 year old Indian male. I was recently making out with my girlfriend while she was sitting on my lap and we both had clothes on. I experienced erection and my underwear and jeans felt wet, probably it was the precum. Is there any chance that she can get pregnant from this, giving that she was sitting on my lap? And should she take any emergency contraceptive pills because we did it 24 hours back from the time of writing of question. She is 20 and probably it was 16th-17th day of her cycle. I would really appreciate an answer as soon as possible please. Thank you in advance. Also I have heard that precum may contain sperms, but I had not masturbated recently (in the past 24 hours).
