unprotected sex

I had unprotected sex about 2 weeks ago & I just worry a lot lol. I’m 18 but my mom is not understanding at all about sex so i’m currently not on birth control. my period is supposed to start in 11 days but i think i’m starting to get pms symptoms. this is not uncommon for me either, my period has always been very irregular since it has started. I still can’t help but worry, does anyone have advice? anything besides buying a test lol like actual advice lmao. and yes i know condoms thank you
