37 weeks and went to a rave SOBER obviously

I'm 37 weeks and I went to a Halloween rave to be a sober whatever anyone needed for my friends but they were all on MDMA and I told them to NOT touch me cause I was so terrified of contracting it somehow, I made sure to wear a tank top, t shirt, sweat shirt, then a jacket that I couldn't zip up. They still touched my belly and stuff AFTER I TOLD THEM TO NOT TOUCH ME. Do you think me and baby are fine? They touched my hands and stuff but when I got home I washed them. Idk I'm just freaking out and wished I stayed home instead of going. I told one of my friends to not do it because then she couldn't touch me and she still did it. They touched my belly OVER my sweat shirt which was fairly thick I guess. Only part of my body they touched that wasn't covered was my cheek and hands but I got mad when they touched my cheek and I tried to not hold their hands.  Someone please tell me if they think me and baby are ok? I sound so pathetic but I'm actually panicking.
