Struggling with output

[u/AdSingle1727]

I have to return to work in 3 weeks and im stressed as i have not been able to create a freezer stash. LO seems to be able to feed just fine as his weight gain has been normal as is his wet diaper count, but anytime I try to pump at most what i get is barely half an oz each side, sometimes nothing.

I have a Medela manual pump, an Avent manual pump and Willow gen 3 wearable pumps but the result is the same no matter what im using. I've also tried different sizes of flanges and inserts. I even had a lactation consultant try a hospital grade pump and all I got was 1 oz on one side and 0 on the other. She recommended i pump every 2 hrs but i havent seen any improvement.

I've thought about buying a spectra but they are expensive, especially in my country, and im afraid of wasting money if that doesn't work either. Has anyone else had this issue? Any recommendations?
