Please help!!

My baby is 2 week old, since birth she hasn’t been able to latch so I would pump and do formula, I stoped pumping 4 days ago since both my breast were extremely sore, super swollen,I had a fever of 102 well technically my ob doesn’t consider it a fever and I was told it couldn’t be mastitis so I stopped pumping and would massage and express my breast which my supply is very little almost nothing by expressing vs pumping. I want to continue pumping but how can I prevent going through that pain again?? I just wished my baby would latch of my breast but she can’t or doesn’t want to IDK. Please help! Any advice?
