Lower supply or feeding more?

Br

So my 2 week old has a shallow latch but seems to be getting better. I’ve been pumping after her feeding to keep up my supply and feed her those bottles because she wasn’t getting enough milk due to the latch. I was pumping about 2 oz after each session but now it’s gone down to .5-1 oz consistently. I think her latch has gotten much better, could that mean she’s getting more milk and i don’t have much left for pumping? Or has my supply gone down?
