Baby weight gain concern

Elizabeth

On the 24th, I have to take my baby fir her 6 mknth check up. At 4 months, she was 11 pounds. When I weigh her at home, she hasn't gained weight. I could be doing it wrong, but idk. She was borm at 36 weeks. When I have to pump, I produce 1 ounce per hour, which I read is normal. Baby nurses every 2 to 3 hours at home, snd she'll nurse from both breasts. At times, usually more at night, she'll get fussy, but she seems very satisfied after her feedings, which are usually around 10 minutes total lately, few times more. I'm worried that her doctor is going to tell me that I have to supplement with formula. I know fed is best, but I really don't want to go the formula way. Please, any advice or reassurance will be greatly appreciated. I am feeling super down right now to the point where I want to cry.
