Hi. im 22. about 5 years back i didnt see my period for over a year. i was prescribed gynaecosid and it worked but it became irregular. i have more or less than 35 days cycle. is there a chance i will be infertile? thanks

Yes for anyone: But there is a good chance you are fertile. Cycle patterns vary and a regular pattern is comforting to some but not a guarantee of fertility. If you are trying for a year or more without success a consult with a fertility center with both participants would be reasonable. If there is an issue with either they can offer solutions.
