Breastfeeding/pumping advice! I’ve done everything!

Someone please give me advice! I’ve been pumping, breastfeeding and formula feeding since my twins were a month old. They are now 4 months old and I want to get them off formula but my supply is terrible. Ive always pumped and breast fed before every feeding. I’ve tried ovaltine, Gatorade, mothers milk tea, fenugreek capsules, drinking more water, flax seed, essential oils, pumping every 2-3 hours, I tried just strictly breastfeeding for a day (didn’t go so good since I didn’t make enough and they just were so hungry I caved and gave them formula), I hand express, I use two different pumps, I’ve tried other powder mixes that’s supposed to help, anything you can think of I’ve tried. I’m lucky if I get 10ml combined from both sides. (Photo is from both sides after a half an hour of pumping and 3 hours after previous pump) HELP! 😭
