Suggest Remedy To Get Periods Without Taking Yasmin

I have "lean" PCOS. I have not had a period in 6 years except the light bleeding induced by taking Yasmin. I also take Metformin for insulin resistance and spiranolactone for hair loss. I do not have hirsutism or acne. I am 27, 5'5" and weigh 115lbs. I want to stop taking these meds and find out how to get my periods back. I am recently married and would like to have children in the future and feel that the longer I keep taking Yasmin, the less likely it becomes that I will be able to conceive. I eat a very healthy diet and exercise every day. What steps should I take to try to get my periods? I would also like to stop the spiranolactone since I could not take it while trying to conceive anyway. If I don't take it, I immediately gain 4-5 pounds of water weight in a day.Thank you!
