PCOS and breastfeeding

Has anybody with PCOS (polycystic ovarian syndrome) been successful with breastfeeding? Had my son 11/22 and have breastfed since - however, I only get at most 1 oz on a side when pumping and have had to supplement due to him loosing too much weight.  Taking fenugreek, drinking mothers milk tea, berry drink supplements, etc. 
Any tips?
