weight loss and fertility

Ashton
I know that being over weight or under weight can decrease fertility. I've also read that even if your in a healthy weight range that losing a few pounds can boost fertility. 
I'm 5"7 145lbs, PCOS. I'm actually very small boned and my problem area has always been my tummy. Would losing 10 or so pounds do any good? I just finished 50mg of clomid with no results, follicles barely grew. I'm just looking for ways to help the meds I'm already on work more effectively.
