How long does it take for my breast to stop producing milk?

My baby is now 7 in a half month old and I BF him for about 6 months. I did not use the rx and just quit breastfeeding cold turkey. At first I had really bad engorgement, but now I no longer have this problem. The thing is that although I am no longer engorged and am no longer leaking or swelling up my breast still have milk in them. I know this bc I got curious one day and squeezed a little and I still had milk in both breasts. Exactly how long will it take for me to no longer have any milk in there period? Also when you stopped BF did you notice that your appetite decreased and you dropped a couple of pounds?
