Help me increase my supply!!

I feel like I’ve tried everything to increase my supply at this point!

My son will be 12w tomorrow and I make around 24-25oz a day.

Almost 2 months ago I was only making 13oz a day.

The thing that helped me increase was frequent pumps and power pumping.

After the slow increase for 6 weeks I’m stuck.

I’ve also tried: fenugreek with blessed thistle, oatmeal, lactation smoothie(brewers yeast, oats, flaxseed, PB, banana, almond milk), Gatorade, mother’s milk tea, body armor, correcting breast shield size, replacing pump membranes.
