Hai. Me and my gf(19) had a foreplay few days ago. She played with my penis and there was semen all around. when I did the fingering I was not sure if the semen touched her vagina but her vagina was wet. Her period date is 17th of this month and she did not get it till date. she is taking a lot of stress since a week. Is there any chance of pregnancy?? Please reply we are really tensed
