The tip just barely went inside for like five seconds and he didn't ejaculate or pre-***, so should I even be worried at all?

Odds would be very low, unless he had just previously ejaculated and then re-entered, which would increase the odds. It also depends greatly on where you are in your cycle. Some times are more likely, others are less likely.

Moved to Pregnancy and New Motherhood because based on your other posts, you are NOT an adult, and cannot get advice in Adult Sexuality.

Unless you are tracking your cycle (and you'd KNOW what your chances are if you were), then we have no idea.

And sorry honey--there's precum there whether you saw it or not.

How about if you don't want to get pregnant, you STOP HAVING SEX?

I got pregnant on THREE forms of birth control. Yes, I was using them correctly. I was a straight A student, a junior in high school, and thought that as long as we were being THAT careful, it couldn't happen to me. Guess what? If you're having sex, it can happen to you!

NOW--Do you want to spend the rest of your life linked to a pot-smoking liar? That's what will happen if you continue to have sex with him, honey.

PS--I got pregnant the second time I had sex, too. It CAN happen to you.

Well, I actually asked this question for my friend, but thank you for the insight.
