Breastfeeding Supply

I’m worried my supply is running low, my LO will be 6 weeks in 2 days and she’s eating every 1.5-2hrs so I’m worried she’s not getting enough at each feeding so I started pumping afterwards to hopefully increase my supply. After her morning feeding I pumped about 6oz, then after her next feeding I only pumped 3.5oz. She was plenty of wet/poopy diapers and at her last check up was 50% for weight so average.

I’m just worried she’s not eating enough, any thoughts?

I’m gonna start increase my calorie and water intake to try and increase my supply too.
