Breastfeeding Question

Kimberly🚮🚮😘 • Momma to Orion, Taurus, opinionated (sorry)

I'm 6 days PP and my milk came in a couple days ago. Today my right breast has stayed sore and somewhat hard all day. I've been pumping because of other things going on, and I'm getting about 2 ounces out of both breasts each time I pump. I don't know if that's enough though. When my son tries to eat directly from the breast he fights me and then he always acts like he's still hungry no matter how long he's sucking for.

Question is, why is my breast staying hard and sore like that? Am I not producing enough milk for him? I am a FTM and have no clue what I'm doing
