Milk supply drying ???

My baby and I have been successfully breastfeeding for 7 months. On Tuesday she only had one really big pee diaper (she sleeps through the night), 1 poo, and 1 small pee diaper. My supply has dropped a little because she sleeps through the night and I work full time so I just pump, and nurse her when I get home. I’m a little nervous and thinking I should just dry my milk up and feed her whatever left in my milk freezer stash??

Has any other mommas had their breastfeeding babies have only 2 wet diapers for 1 day?
