Pregnancy Risk. There risk of pregnancy?

I am a PCOS patient since 5 years. I was on periods since 2 months(mild bleeding daily). I am a virgin. Since a week, my boyfriend and I have been making out(rubbing penis, fingering). Attimes he masturbated and ejaculated on my clitoris/vaginal lips and few of the times he fingered me but I don't remember clearly whether that was after washing hands/only wipping with a towel.But yesterday,he just wipped his hands,with which he had rubbed the semen on my body, with a towel n after 5-10 minutes, inserted the fingers in my vagina completely. And for the first time, he tried inserting his penis(with which he had ejaculated 10-15 minutes before and just wiped penis tip with a towel)inside my vagina, but that went about 40-50% inside my vagina, but he immediately pulled it out after that. And 5 hours after this fingering and insertion act,I took an "unwanted-72" pill without vomitting yet. is there risk of pregnancy? i've pcos n was bleeding then. aftr takin pill, i didn't get periods today
