Effective diets for PCOS

Ladies that are suffering from PCOS, what kind of diets do you all follow? I was diagnosed at 17 but it seems since I gave birth to my son in 2015 the symptoms have gotten worse. I was bleeding for 15 days straight even went through a 4 month supply of tampons during that time. The doctor prescribed me progesterone tuesday to take because he said right now I'm just bleeding but not shedding my lining. After the progesterone I will bleed again to clean my uterus out and then start birth control to regulate my cycle so I can have a period every month and not every 6 months. My question for you all is if possible can you shed some light on diets that help with losing the weight along with hopefully making the symptoms of pcos disappear. Thank you.
