HELPPP

okay so if hypothetically I just had sex a few hours ago and the dude came near my vagina I think and I wasn’t on birth control and his condom broke, can I still get pregnant?? And hypothetically I’m 17 so can pharmacies even give the morning after pill to me?? And hypothetically I’m supposed to get my period next week tho so I don’t even know if I can get pregnant cuz this app says there’s only a 3% chance😭😭😭 I feel so fucking stupid right now my head hurts.
