One night stand unprotected

Well on 4th of July there was this guy I was hanging out with, I didn’t even like him but he kinda pressured me into hanging with him and his friends. He is also the best friend of my ex who was my first love, we were together for 6 months until he cheated....wellll enough with the backstory... Porter and I fucked in the woods, I was riding his dick and this nigga didn’t pull out, I’m so scared.. I get my period in 2 days so hopefully it comes.. pray for me. I’m only 14, and he is 17. That’s a big case.
