Stop Milk Production. Help!

I have decided to solely formula feed. This decision comes from not wanting to put added stress on myself as I’m at risk for PPD. I feel in order to best care for my baby, I need to make my mental health an equal priority.

Anyway, I put off researching the best ways to cope with milk production. I’m 4 days pp and they’ve just now begun to hurt and get engorged. Still nothing has come out.

Any advice on how to ease pain and make it all go away? I’m wearing tight sports bras, that’s about all I know to do.
