Hi, i'm desperate. About 3-4 weeks ago, i masturbated and i remember i washed my hands then i went outside and after 20 min i met with my 16 years old gf and after another 10-20 min i fingered her(first time for her). The temperature was a little cold, about 5 grades Celsius and my hands were dry and it couldn't be seen any thrash of sperm. Now her november cycle didn't come yet (it's late for a week and some days, it's irregular), last year she didn't had in december. I wanna know, it's there a slightest chance of her being pregnant even if let's say i didn't wash my hands?
