Only 3oz max per pump-mini rant

I only get 3 oz max per pump and that's rare. On average 2oz. I am already taking fenugreek and upped my dosage from 2 to 3 pills 3 times a day. I drink water all the time but nothing seems to help my supply increase. I recently got a double pump as a gift and have ordered the tubing etc so i can use it. I hope this will help. My little one, currently 4 weeks old, drinks 4oz a feeding, so i have to supplement with formula which is not the end of the world but still not how i want to feed baby...
