How to increase and even supply?

I need your help, mama’s. My baby boy is a month old and eating 4oz at every feeding. The most I pump is 3oz. How can I increase my supply. I eat oatmeal and try to drink lots of water. I just got some chocolate drink mix with fenugreek in it. Anything else I can do? I pump ever 3-4 hours and have tried pumping every two and power pumping and didn’t really notice and increase...

I would appreciate it!
