Has anyone ever experienced a hormone imbalance effecting you milk supply?

I’m a FTM with a almost 1 month old. We have had a very rocky start at breastfeeding landed us in the ER for his weight lost and dehydration.

We are now supplementing with formula while I try to figure out my supply. For the last 3 weeks I’ve been going to a breastfeeding resource center but I haven’t seen an improvement. I produce almost nothing. 10-15 ml from my left and 1-2 ml from my right. The lactation consultant at the center had mentioned a possible hormone imbalance. Has anyone had any experience with this?

Is this something I can ask my ob to check or should I go to my primary?

Is this fixed with medication? Or diet change?
