My right breast isn’t producing milk?

My Breasts are engorged but my right breast isn’t producing? Is it too swollen? They both got very swollen, hard & painful yesterday. I stopped breast feeding yesterday and switched to pumping because it was a little less painful. I also supplemented with formula so maybe I was pumping a bit less than usual for that day. but I’m currently 4 days postpartum.

Sorry I keep posting on here 😬 I have no one else to ask :(
