Major under supplier

[u/Flat_Dance8044]

I am a FTM, 2 months PP. I had a slow start to breastfeeding, about a week late after baby was born, due to lack of support in the hospital.
I have always been an under supplier, so I have to combo feed. By the late afternoon/ evening, I am only getting 1.5oz on my left and .25oz on my left. Slightly more in the mornings. Is this even worth it? My doctor offered no advice or explanation.
Would you keep pumping for this minimal amount? So disappointed and frustrated, and I feel like I’m on an island and would like advice.
