Milk issues

Samantha

Baby was born at 36w and 5 days. After we got home started supplementing with formula because she had lost too much weight and milk hasn’t fully come in. My supply has not increased to match how much she needs to eat now at 7 weeks old. We saw a lactation specialist and she’s only able to get an ounce when she nurses, and that’s about how much I get when I pump. I’ve been drinking pink stork lactation tea, taking fenugreek and goat’s rue supplements. My supply is still the same. I’m still supplementing with formula to make sure baby gets full. Does anyone have any other suggestions to boost supply? I’m ready to just give up and exclusively give formula😔
