Ok, First off, i want to say thanks to anyone that gives me any info, and please help me out. another thing, my Girlfriend has irregular periods. we were messing around in my basement and she said that we should have sex, but i didnt have a condom, so i said no. then later on i said we could but only a couple of times in and out, ya know? i was a virgin and so was she so we were both curious. but i was worried about precum having sperm in it so thats why i said no the first time, but now i said ok. so i was about 3 inches in and she told me to pull out and i asked her why and she said cause it hurt and then we found out she was bleeding. so my question is what are the chances of getting pregnant with a girl that has irregular periods, having first time sex for both people, being in her for 10 seconds tops, not being in deep, and not ejaculating inside her. i love her so much and dont want to see anything happen, but if it did, i would be there...im so worried and would really appreciate some help.
