pregnant?

If you don’t like “dumb” questions, please ignore my post, because I have nobody else I can talk to, and this is my only way of asking. Thank you.

—On September 29, I had unprotected sex with my significant other, but it’s not as bad as you think, I don’t know. I wasn’t penetrated, but I did rub my vulva on his penis, and I know he came a little bit before getting to that point. I got my period the week before, September 19th, so now I have to wait until I get my period, if I get my period. I’ve done my own research, and I’ve found a lot of various responses. Some people stated that you can’t get pregnant without semen getting into the vagina, but others said you can get pregnant with pre-ejaculation on the outside of the vulva, though the chances are slim. All I can say is, I’m scared. I’m scared because nobody knows I have sex, especially my parents. My parents, and his, believe in abstinence. So, you can already assume how things will go if I do turn out pregnant. The point is— I don’t know how to check if I’m pregnant, I’m getting my period sometime next week hopefully. It’s been 2 weeks since I had sex, is there a way I can check if I’m pregnant? I just want the reassurance, because I’m honestly scared. Thank you for reading:)♥️
