I know I have had a bunch of pumping questions lately but today is my first day back at work!

I am curious how much you can pump at work? I am hoping to continue using just pumped milk (not supplementing with formula) but am nervous that I will not
produce enough at work for the next day. Do you have a pumping schedule or routine that allows you to produce enough for daycare? I was extremely anxious coming back this morning and, as a result, hardly pumped anything before leaving the house. I am hoping that's just due to the nerves and getting into our new routine, but I'm hoping to pump enough milk for daycare.
