idk what to do

I am five days late on my period and idk what to do. I did have sex but he didn’t you know but i know pre cum can get me pregnant so I know that me being pregnant is a possibility, but I don’t know if I want to know if I actually am. Mind you I am in high school, and I know that my actions have consequences but my boyfriend has a lot going for him with sports and he is going through stuff with his family as well. Whenever i’m late on my period it never lasts this long and I think I might have been experiencing symptoms.If I do find out I am I don’t know if I should tell him, I don’t want him to worry about anything more than he is right now, but at the same time I feel obligated to. I’m waiting until a full week has gone by to make my decision on taking a test. If anyone has any type of advice that isn’t shaming me for having underage sex please tell me because I am honestly scared.

update on this: i got my period a week after posting. and i didn’t take a test. but thank you for all the help ❣️ truly meant a lot
