Anytime a man ejaculates inside of you, you have the possibility of getting pregnant. Take a pregnancy test after you are thru with your period. If your not pregnant I would highly suggest you buy your OWN condoms so if your partner doesn't have one you do!
This is TMI and a question like this should be googled privately for an answer, if an answer via the Internet is what you want. Otherwise, make a doctors appointment and ask your doctor. If you don't know that anytime a man ejaculates inside of you, there is a possibility of getting pregnant, then you are FAR too young to be having sex, much less raising any children!
