Milk supply

I am 7 weeks pp and think my milk production is dropping. I had a good supply in the beginning. My son gets fussy sometimes while nursing, squirms, and sometimes unlatches himself while crying. He just doesn't seem satisfied. I know your supply drops midday but it's gets frustrating to the point where I want to stop breastfeeding altogether. I just started supplementing him with formula to make sure he's satisfied, which he barely drinks. It's like he prefers the breast milk. Do you have any recommendations on how to boost my supply? Also when I tried to pump. I would get .5-1oz out the left and 2oz out the right and my fat content is barely there.
