I M Suffering From Pco. Last 2 Months I Was

I m suffering from pco. Last 2 months i was having regular period. Bt this month i didnt had ma period. It was supposed to me on 25th nov bt till now it didnt came. So i took primountn on sat. Can you suggest how many days should i take the tab. Its the 3rd day today? Will i get ma period once i stop d tabs? I had a sex with ma husband so is there any chances to get conceive?
