I finished my period december 31. My boyfriend and I were fooling around on January 5th, (since I'm a virgin we did not have sex). He dry humped me and after he moved away he had a huge spot of cum on his jeans (I had jeans on too). Then after I gave him a hand job and I had cum on my hand, I wiped it off with tissue. 5 minutes later I was home, I went to shower and I'm not sure if I washed my hands. I'm scared while washing my vagina his cum might have entered my vagina. Is that possible? Could I be pregnant from the cum on his jeans (would cum go through 2 layers of jeans and underwear)? I took next choice January 7th within the first 72 hours. I have no symptoms I'm just worried. My period is due this Friday, my breasts feel heavy. Please help

I'm a virgin and come from a very conservative family. And my boyfriend and I are not ready for marriage and parenting yet. Please help
