Back at work Pumping

Just wondering if anyone has had a similar experience. I am back at work starting today. My baby has a tongue/lip tie and is a bit of a lazy nurser, so while at home I needed to supplement him with 6 ounces of formula a day. However, now that Im at work Im wondering if Ill be able to increase my supply or if its too late?

I am at the liberty of pumping in the privacy of my office all day, so I could definitely pump every hr if I needed to. Anyone have a similar experience and has seen an increase in supply?

Any tips on how to boost? Or am I stuck at a low supply since its been past 6 weeks to establish? He will be 9 weeks tomorrow.
