Milk supply

Shiny

I’m 5 weeks postpartum. I’m only pumping 2 oz in an entire day. My baby was having some latching issues some I went to pumping. I was originally pumping 4-5 oz a session and now I’m down to 2 oz in an entire day. Is it possible to bring my milk supply up again? I admit I did not pump for a couple days because I was very emotional. Someone please tell me I can do something... I feel so guilty. My daughter is not reacting well to formula.
