Exclusively pumping - decrease supply after mastitis

Layla

Hi ladies, I got mild mastitis in one breast a few weeks ago and finished the course of antibiotics. My supply hasn’t been the same after. I will admit that I tried to extend between pumping sessions to 4-5 hours rather than 3 and feel like that messed me up also. I pumped at 11:30p and had an alarm for 2:30 a but literally nothing when I say nothing I mean drops to nothing came out do I went back to sleep and it’s currently 4:47a and I’m trying to pump again and I’m still getting drops. Anyone know why? Or know what I can do to get it back up. I was producing between 3-6 oz each pump before.
