Someone help!!!!!

My boyfriend and I were messing around like 2-3 days before my period was supposed to come and the condom broke but he wasn’t inside of me, I’m only 16 and not ready to be a parent and if my dad finds out he will kill me 😔 idk what to do and I can’t get a pregnancy test bc idk anyone I could trust enough to get me one. And I don’t have a job so I can’t go and get one and everyone at the dollar store knows my dad very well so I can’t just walk in there and buy one. Idk i I’m pregnant or if my period is just late because I had sex. Someone help me!
