Is it possible to get pregnant if my boyfriend very quickly touches his boxers which may have had a little tiny bit of precum underneath, and then fingered me a few minutes later, bearing in mind he wiped his fingers on his trousers before he fingered me? He doesnt remember it being wet, or even touching it, but I'm still worried, and it's stressing me out. I'm now four days late for my period and am getting worried, I don't know what to do, please help? Thank you very much :)
