Never experienced before, worried! Please help!

I am five days away from my period now, but I’m having cramps like i’m ovulating. I know the difference between period cramps and ovulation, plus I ovulated a little over a week ago. I feel it in my left ovary and my nipples/boobs are sore. I haven’t been feeling my normal pms symptoms, I’m fairly regular and my periods are sometimes a day or two off nothin serious. I am a virgin, but I did get fingered a month ago and I’m paranoid that maybe he touched himself and got precum on his fingers? (I know that sounds dumb but my anxiety always gets the best of me.) I got my period two days after that happened and it lasted its normal time. Help!
