Breast feeding/ pumping (let my self down)

Mercedes✨
Is a lot  harder thanI thought it would be this time. I had so much confidence I could do it. It took me 4 days to get my milk my baby was not happy so I started a supplement formula. On top of it I couldn't get her to latch correctly it was in tons of pain so I decided pump til my nipples healed. She latched after but just didn't like it. I've got milk just not as much as she's calling for. Now she doesn't even want my milk idk what else to do I don't want to give in to formula : /
