Pcos mommas.... help

Shelby
Hey mommas out there!! I have a question for those that are and have breastfed your little angels. I'm having problems pumping and feeding more than 3 ounces at a time every 3 hours. When I came home from the hospital I was able to pump 5 ounces which I assume that's what my little man was getting. He had a doctor's appointment almost 2 weeks ago and he lost weight and so I am not sure why my milk went down other than they say us women with pcos could have issues with our milk supply. So my question or questions would be for those that have or had the same issue what did you do to increase it and produce more than baby needs? I absolutely hate supplementing with formula, it takes away some of my bonding time with him. 😌 Also, my left breast produces only half of what my right one does, so how do I get the supply up in there too? I have tried to feed longer on that side. Please help Thank you
