She tells me that she could be pregnant.. Shes 1week delayed.. Its her first time having sex and technically.. Unprotected.. I didn't use condoms because logically.. I always do the normal way.. Withdrawal.. Her last period was on march 27-30 and now its may 5.. Still no menstruation.. She tells me that her breast were slightly aching and her down there also aches.. I wonder why it happens.. Do precum could make a baby?? Or wait another week and use pregnancy test kit
