Up supply

I feel like I’m trying all the things to help up my supply. My only good pump of the day is first thing in the morning and it’s only 5 oz maybe 6 on a good day after that I’m lucky if I get 3 oz a pump. I’m eating all the oats, staying well hydrated.. even got the milky mama emergency brownies. What else can I do? I power pump 2x a day even.
