i doubt you could be pregnant...just calm down and wait for your period. if it doesnt come a week or 2 after its suppost to then take a couple home pregnancy tests(taking 1 can give you a false negative or false positive so just to be safe). so unless your hands were down there going pee and your hand accidently touched with that crap on it or something(idk just a possibility) then i dont think you are.
You can only get pregnant if semen/sperm comes into contact with your vagina. If that did not happen, then it's impossible for you to become pregnant. Try to relax and wait for your period to come. Don't stress out too much because that can cause your period to be late, which will only further stress you out. If your period is late, take a home pregnancy test. Though from what you wrote, it doesn't sound like any semen/sperm came into contact with your vagina, so you're not pregnant. Take care.
