Too much milk (12 days postpartum)

Milk came in around day 4. Day 5 to currently Im unbelievably engorged. They are huge, and hurt so bad. Baby can't latch until I express a little. She seems to eat great and is gaining weight, she doesn't empty the breast though. I use my hakka on the opposite side while I nurse and get about 4 to 5 oz each time. Is it normal to still be engorged? I dont remember this from my last baby, it only lasted about 2 days...

Should I wait a few days to see if it subsides or should I try some block feeding to reduce the amount Im producing by a little?
