We had protected sex today. I was wearing a condom. When i was done I immediately pulled out ( penis still erect ) , but then my gf noticed some wetness on my testicles it seemed that the semen may have leaked from the base of the condom or was it her lubrication that got in contact with my testicles ? And also there was wetness on the Condom's reservoir, but the semen was collected properly inside the reservoir. I am really confused as to what that moistness might be. And if it was semen that leaked from the base of the condom what are her chances of getting pregnant ? Her last period ended on 12th of June and she has irregular periods so I cannot calculate her ovulation window. What are chances of her getting pregnant in this case ? Should she take an ipill ?
