Increasing milk supply

I’m 5 weeks pp. I didn’t pump much for the first 2-3 weeks. My milk supply is super lows since last 1 week I’m really consistent. Trying to pump 10 times a day, 1:30am, 4:30am and then from 8am to 10pm every 2 hours. I drink and eat things to increase my milk supply. I have good size of flanges. Had 24 in hospital then I measure and found out I’m 15. Massaging and warming my breast doesn’t really help or at least I didn’t see any difference. I do body to body time with my baby and… nothing really changed. I pump in 24h around 1,5oz~2,5oz. My baby doesn’t wanna stay on breast because I can not satisfy him. He eats each session 4oz. Idk what else I can do. My doctor today told me if I’m a whole month pp and nothing change than I won’t have milk. That made me sad cuz I really don’t want to give up and I want to breastfeed my baby.
