I’m so stressed and terrified someone please help me

So I am a 16 year old virgin and a month ago I decided to do other things then sex so my boyfriend rubbed his penis on my vagina I was off of my ovulation days and when we did that I was 9 days away from my period starting. I was so terrified that I was pregnant but that period started early. But now this month my period was suppose to start today and it didn’t and I’m freaking out because I’m afraid that I’m pregnant from the last time I was scared but then I had my period but now I’m scared that I had a period but still got pregnant because I heard that can happen. And now I’m really stressing out and am very scared to the point where I can’t stop crying because I’m afraid I’m pregnant. The only thing I’ve done recently since my ladt period was jerk my boyfriend off and when he cummed I immediately washed my hands right after and didn’t let him touch me and I didn’t touch myself so the only thing I can think of is from the last scare I had. Someone please help me because I can’t stop crying and am so confused on why my period is going to be late because usually my period are always on time or early.
