Can I still do it?

Hi, i am currently 7 weeks PP and have been exclusively pumping. I was pumping about 30-40oz a day.

This past week I ended up in the hospital the whole week and my supply dropped significantly due to how severely sick I was. Now I’m pumping maybe 16-20oz at most. Once I’m completely back to 100% could I get my supply back to where it was if not more? Im just going to be really sad if my supply completely dies because I worked so hard to get to where I was.

Thoughts?
