Help, Help

Ladies I need some advice about a week ago my boyfriend fingered me and I gave him a hand job. After he cummed I helped clean him up with a paper towel and I grabbed the ends of it and through it in the back end of his truck. I washed my hands with a bottle of water after that. But then I itched myself? Is there 
anyway I could be pregnant??? 
I did get my period a few days later!?
