S.H.
Milk... takes AWHILE to dry up.
I still had milk in my boobs, even several months, after my kids weaned.
MONTHS after.
But I did not get engorged, because my kids weaned, gradually, and my breasts adjusted.
You may also check with your Doctor, just in case you have Mastitis.
Your breasts are hard in some places. You gotta get it out.
Go in a warm shower, and hand express it out.
AND see your Doctor and there are meds that will dry you up. Too.
But I would make sure, you don't have a Clogged Duct or something... and see a Doctor.
