Well the percent of getting pregnant in that case is nearly 90%, however do not be alarmed by the number as in each case the siuration may be different as Mistakeguy said)
thanks, I guess i will wait and see and man up if something happens.
A lot of things play a roll in finding this out.
Women only have a certain time during the month that they will get pregent (ovulation). If you hit that time of the month and shes not on birth control and has no known fertality problems then I would say your chances are high.
However, its tricky to tell how likely a girl will get pregnant. It really is one of those "wait and see".
