precum&pregnancy

if my guy has had ejaculated sperm on his hands, and then messes around with me, is there a possibilty of pregnancy, and i had previously finished my period the day before?

Yes it is possible to become pregnant in that case. Precum does contain trace amounts semen and even this does have the chance of getting you pregnant.

Also if your guy has/ had cum on his hands, and he plays with you , it is also possible because the semen can live outside for a short amount of time, and as long as it is near the vagina opening , it can swim up and in.
