When will my milk dry up?

I have been pumping for my son for 6 months. He's received about 90% of my milk while supplementing with formula. For personal reasons, I've decided to exclusively feed formula. Ideally I would've loved to BF for as long as we could. But he has breast refusal... 😞. Long story short it has been a week, and my breasts are still leaking, and I can feel that they have milk. Not SO much that it hurts, but I thought a week without pumping would have done the trick. Any tips please! TYIA
