Vitamins for ovulation and health.

Andrea
Hi there I have pcos and I'm over weight roughly 18stone I know how to loose weight but I've always been a one for comfort eating . As I have no money left this month I'm doing small other changes such as smaller portions more water etc.. 
I was just wondering if there are any vitamins to help ovulation, boost mood and to overall make inside my body healthy. I have never been pregnant ever so I will try anything. 
Thanks for reading :) x
