On 7 June Friday night I did masturbation and my left and right hand smeared with a sperm after that I washed both my hand and my penis . The next 8 June morning I took a bath with water and soap.  Then I went to my daily routine in this routine, I traveled some places and while traveling I washed my hand with water. then I went to a restaurant where I wash my hand with hand wash and water. after eating I wash my hand with lemon and hot water. then I reached home and took a shower with water and soap. Then I reached my girlfriend's home where I use a hand wash and water to wash my hand , after that I insert a finger into her vagina to give her pleasure i use my right hand's index finger and left hand's middle finger for a fingering. The duration between my last night's masturbation and inserting my fingers into her  vagina the duration between two acts is 15-16 hrs In this situation can she get pregnant ?
