can i still get my milk up?

sa

i breastfed my baby for only about to two weeks before i started using formula and now that’s pretty much all she eats because i would only nurse maybe once a day. i want to start breastfeeding again but i barely have any milk in my boobs now. i’ll hand express and it’ll just be a couple of drops. i know i can just nurse my baby but since i don’t really have any milk she’ll maybe wanna stay on for a minute or less. i’ve tried pumping a while back and it was working out good but then i had some problems and i stopped pumping. what can i do to get my milk back up and is it too late?
