Pre Cum and Pregnancy

Tia • I am 17 and from Georgia. I love books, people not so much but i am open to friendships!
I just wanted to post this since I have seen a ton of people comment on other people's post about Pre cum getting you pregnant. Pre cum itself can not get you pregnant. If he has ejaculated before and did not pee after. There is a possibility of pregnancy because the pre cum could bring up with sperm. Thank you that is all.
