Engorgement only in one boob

Taylor

I need help! My right side always seems to be engorged. I put the hakka on there and nurse from my slacker boob to try to relieve some pain. Is that causing it to be worse? What can I do to stop the engorgement? Baby is only 12 days old and it hasnt been engorged like this since like day 5. Which then i just pumped and it seemed to level out, but ive been pumping this one now for 2 days and still seems full.
