Can I get my supply back??

I was exclusively pumping the first 10 days because my baby was in the NICU. it's been over a month and we've been going between breastfeeding, pumping and formula. I had some issues the last week and we've had to supplement a lot more with formula than I wanted. Now, when I pump I barely get anything and she's never satisfied after nursing 40 min total). I really want to get my supply back so I'm going to pump every time I feed her eight to ten times a day like it says. Can I get my supply back ?! Help 😭
