Going back to exclusively breastfeeding ??

Katiana.
Is it possible to try again to exclusively breastfeed my 1 month year old? I nurse all the time and she gets so upset because she's not getting enough milk to satisfy her. She is latched on properly. And when I pump, I get 2-3oz on each breast. So not what I planned for my child being a FTM. 
I had to supplement with formula at nights But I hate it. And I just want don't know what to do. I tried Mother's Milk, drinking water, 3 -water bottle a day. Taking Fengugreek pills twice a day and making a oatmeal and grapefruit juice smoothie. But nothing!! I pump to feed her and try putting her in my breast first but she struggles to pull milk out. So upset and depressed
