manage pcos

I went to the doctor last October and she told me that I had cysts. They did the blood tests and everything was great except she said my insulin was a little high, just to lay off the carbs. I did a little research(also asked 2 people with cysts) and found out that even if you have cysts, you may not have PCOS. I was having a problem with my period only really after my first visit with this new obgyn. After I finally calmed myself down, all was fine. My period is normal, I haven’t shown any signs. I am overweight, but it’s because I didn’t diet well enough/or excersise enough. I have been steadily dieting and working out. Any ideas??
