Taking homeopathy for PCOD. Pcod?

Hi, I do not get periods without medicine almost from the starting and i have been diagnosed with pcod 4-5 yrs back..tried allopathic medicines in 2012,but no results found,then I switched to homeopathy,took it for 1 year,periods dint come,atlast doctor prescribed duoloton for 3 months.I got my periods for those 3 months,after which I changed to another homeopathy doctor,now it's again 5-6 months I did not get my periods. Both homeopathic doctors are good. Now should I switch to allopathic medicines which I personally don't want to or else what could be the reason that homeopathy couldn't treat my pcod yet. Also wanted to know can homeopathy cure pcod ?If yes then generally how much time does it takes to cure someone's pcod ?
