Talk to Gynecologist on Polycystic Ovarian Syndrome (not Sure)

I always had a normal period once in a month till the age of 24 then I missed period for two months only once at the age of 24. Every thing was normal but suddenly I got real bad acne. There was a homeopathic doctor who saw me and suggested some medicine and it worked like magic for my skin the acne was over after almost 6 months of pain and depression.

But now I am 28 and i have been gaining a lot of weight from around 1.5 years. I was in range of 70 to 75 kg which is still much for my height as I am only 5"2 but now I am 82 kg which is way much and my periods are very irregular. I got only 2 periods in past 6 months. I never went to a doctor. Because I don't want to go on a pill. My acne is not bad but there are a few pimples on my face here and there. Losing weight was very easy for me once but I have been on calorie deficient diet from a long time now with no affect.

I stopped the dieting after I got fever and viral flu and cough but I now get extreme hunger pangs, motion sickne
