Period late...

So I lost my virginity on May 9th. Technically it was a one night stand but that’s because we had to stop talking to eachother after due to the fact all the girls around me liked him and some got so jealous they even threatened to report him to the cops (I’m 15 he’s 18) because I told my best friend and then she told her boyfriend who told everyone. So the guy I lost it to lied and said we didn’t have sex and I only gave him a blowjob. We don’t talk anymore and I don’t want him in my life but my period was supposed to come last Thursday. We didn’t use a condom and idk if he pulled out. I’m freaking out rn cuz I told another one of my best friends that my period was late (I’ve known this girl for 4 years and usually tell her everything) and she went and told the guy’s best friend who’s threatening to tell him. It’s a whole big drama but I’m getting really nervous about my period now. I’ve been having mood swings, been really hungry, been experiencing a lot of discharge, and some more symptoms. Idk what to do
