Just wanna make sure this is normal

Before i start I’m a virgin so i know it’s extremely unlikely it’s anything other than pms but I’m paranoid and want to make sure. Me and my boyfriend often mess around but I’m not ready to have sex yet and i want to be on bc before that step. The absolute worst that has happened is he may have had a trace amount of precum on his hand when he touched me down there. But i always make him wash his hands first. I’ve had regular periods but I’m a week out from my cycle (I’m on cycle day 18 it’s coming in 6-12days) and I’m super tired and I’ve been feeling crampy and I’ve been getting this pain in my lower abdomen to my pelvic area. I’m getting screened for endo soon because of some of my period issues and I’ve taken preg tests and been to the dr to be absolutely sure and careful and they’re all negative. Is it normal to pms 9 days out?
