you can get pregnant anytime you have unprotected sex,I have got pregnant on the last day of my period,strange but true.When I was reading and researching,I learnt that women have got pregnant before a period,do some googling ,you would be surprised at what you find.
just because women say its not possible doesnt mean it is,many are defensive when they learn that I got pregnant on the last day of my period,but hey anything can happen.I have always got pregnant right away no matter what stage of the month we have been in,I am very fortunate like that.
good luck x
