Not taking anything for PCOS

Nici
I've known since I was 14 I'd have difficulty conceiving but I only found out 2 months ago that I have PCOS.
My doctor said I need to lose 3 and a half stone before she will put me on any medication. I personally don't think I need to lose that much, im only a size 14. She reffered me to slimming world, which is carb based which we should avoid. So, I'm just wondering if any of this sounds right to you guys or have I kinda just been dismissed by my doctor?
