Low breastmilk supply

I am 22 days postpartum and am struggling with low supply. I pump around 30 ml a pump and do it every 2/3 hours. Daily, I yield slightly more than 300ml. I even invited a lactation consultant over, who taught me pumping techniques to increase milk supply….i also tried lactation cookies, green papaya fish soup, and am currently taking fenugreek and domperidone. Do you know if milk supply is expected to increase after 1 month? My last resort is to try the almond milk from 2nutguys
