hi i'm 26 yrs old diagnosed with polycystic ovary.I'm trying to get pregnant. My ob prescribed duphaston 10mg taken once a day for 8days and took it only for 2 months. I stopped for 3 months now.and I've missed my period for 3months.Can I start taking it again to have my regular menstruation as well as treat my polycystic ovary? When do i take it, since my ob counted 20days from menstruation before i can take a pill.?I'm confuse on the process.please help.Thanks.
