Help!

I’m 2 weeks postpartum today and I just feel like I’m never going to be able to not supplement with formula. I’m pumping ever 3hrs, 20 mins long each time. I’ve done power pumping maybe every other day. I’m earring milkmaker cookies, drinking LOTS of water ( at minimum 100oz per day ) and still am only getting 1-1.5oz per session. Specifically 25-30mls from my right boob and only 10-20mls from my left. I had a clogged milk duct a few days ago and fixed that which that pumping I got 2 oz which is the most I’ve ever gotten. Is this normal? Will my milk increase more or am I doing something wrong??
