Is Pregnancy Possible After Having Sex While On Gynera For PCOD?

I'm suffering from polysystic ovaries in the last 5 months. I'm having BC pills that prescribed by a GYNE consultant. I started to have Diane 35, Yasmine then Gynera. I had my period regularly every 28 days and last between 5-7 days. I'm just done with my last period, but I had sex in the last day of it whiche's the 6th day. In the 5th day I started to take Gynera again. Is there any possibility to get pregnant in my situation?
