Any advice?

Baby girl just turned 1month old. I'm only pumping about 2oz on right breast and 1 oz on left early in morning. Throught the rest of the day (pumping every 2-3hrs) I'm only getting about 1- 1/2 oz total. I drink plenty of water & body armor drinks, have tried power pumping, nursing teas, and currently trying emergency brownies and supplements from milky mama. And even put baby to boob sometimes. Nothing has increased my supply. Is this all I will produce or any other tips or tricks out there. I really dont want to quit or give up when I go back to work in a few weeks but im thinking so much time and work for this small amount may not be worth it.
