Am I pregnant?

I am currently 15 I just broke up with my bf bc I sneaked him into a friends house and we had sex with no protection bc I just got off bc( birth control) well we can’t see eachother anymore so I broke it off it’s been ab 3 weeks and I am experiencing tiredness, eating A LOT, Using the restroom more, nipple tenderness , headaches, and trouble sleeping, and I’m 12 days late for my period. I can’t get a test bc im literally not allowed to go anywhere without my parents until I’m 18 so they say and I’m really scared so if y’all could help that would be great!
