Hey, I have been taking Diana 35 since 6th April, 2012. My menstration for this month is due either today or tomorrow. I had unprotected sex last night, meaning, the last time I took a Diane 35 tablet was last Thursday, that been the last day for the last tablet for that last cycle. Can I become pregnant now? Or can I take Postiner 2 to prevent the possibility of being pregnant?
