Drying up, help!

My milk is drying up on its own. My baby sleeps through the night and nurses about 8 times a day. But I have to supplement after most feedings after finding my baby lost weight. 😳😭 I am pumping right now and seeing that I just don’t have much milk (I already know that from having to supplement so

Much at this point) aside from an insane pumping schedule again is there anything else I can do to try and get my supply to at least stay? It happened really suddenly at 5 months old for my baby.
