So I'm 14 and me and my boyfriend had sex like 2 weeks ago. I'm supposed to get my period in like 10 days and it's usually pretty regular. I am kind of worried about one thing though. He put it in for like 2 seconds but not even all the way like less than an inch.....is there any possible way I could be pregnant from pre cum or something? We used a condom and it didn't break. But I wasn't on the pill, so I'm a little freaked out.
