feel like i’m failing her - milk supply low

i’m 2 weeks pp failed vaginal birth turned to an emergency c section....had to supplement my daughter in hospital due to my being anemic (almost needing a blood transfusion) and fever... we are home now and things are much better just no human donor milk available.. we’ve had to continue to supplement with formula.. i wanted to EBF..as i heal little by little..but we need to make sure she’s fed..it’s been working so far she’s passed her birth weight.. but i’m still having trouble BF to completely satisfy her...my midwife told me to start pumping to increase my

milk production.. but only quarter an ounce after 1.5+ hour of pumping both breasts...this is so hard... only she can truly pull the milk from me...i'm sure she's pulling more but after i Bf for most of the day she still is hungry in evenings... the LC does weighing before after feeding ..it's just so expensive...

is there anything i can take to increase my milk?
