Need help! Period is a little late.

A few days ago (Monday) my boyfriend came to visit me. We were just chilling and I decided to touch him down there. It wasn’t for too long, maybe a minute and there was a bit of pre cum. He always tells me to wash my fingers/ don’t touch my vagina area until I’ve washed my hands after touching him but I wasn’t planning on touching myself anyways so I just licked my fingers. Maybe two hours later? He left and I just folded some laundry, watched some anime and made some food to eat. I went to bed around 11 and touched myself before I went to sleep. My period is a day late. I started getting cramps on Thursday and thought my period would come then because I usually get really bad cramps right before my period but it didn’t. I also had average cramps on Friday and today but still no period. I usually wouldn’t worry because it gets wacky sometimes but I’ve been stressing a bit because I’m not sure if there could’ve still been cum on my fingers when I touched myself at night even though I had been doing so much other things. I can’t even remember if I washed my hands at any point during before bed (I probably did but I’ve been stressing and missed that point) It’s still really early in our relationship so we haven’t had sex yet. I’m just wondering if I could get pregnant if cum was on my fingers.

Sorry if this post was a mess :)
