TTC with PCOS

I have been trying to conceive with my partner for over 3 years now with unfortunately little luck. My preference would be to conceive naturally without the help of drugs that the doctor has recommended, however I want to take control of my body and how it works and I don't feel I can do that with tablets. 

I have PCOS, which I was diagnosed with at 16. It was a confusing time, not really knowing much about PCOS and the doctors being so sparse with information. I was first told I was going through an early menopause.... At 16! 

I came off contraception about 3 years ago with the view of conceiving mine and my partners first child but it has never happened. I have noticed that I am having more frequent periods, something I never thought I would be so excited by! I am taking folic acid every day along with other vitamins, I go to the gym 3/4 times a week and have lost weight which I hope is the reason behind the more frequent periods. 

Can anyone offer any advice on the best ways to conceive with PCOS?
