Stupid question

I know this is a stupid question but it's the last one I will post for a while since my boyfriend and I broke up two days ago. But three days ago I gave my boyfriend a hand job after him not being able to do it himself for three days straight. I can't remember any cum getting on my fingers but say for example it did and I wiped my fingers on the bed sheets is there any way that I could get pregnant from touching myself? I don't go inside myself I only touch the outside of my vagina. Plus I Am on the pill. Also if I am on the pill would touching myself in this way with cum on my hands cause pregnancy? I just really REALLY don't want to get pregnant at my age. Also I have really bad anxiety issues so plz be nice with your responses. I didn't get the best education so I don't really know these things?
