Supply increasing slowly

Idk if I have low supply or not but I was never pumping close to what my baby ate till a week ago. My baby eats an average of 25oz a day now and I just started pumping that recently and I'm so excited! Nothing was working to boost my supply. I tried almost everything and the only thing that yielded results (and very slowly) was increasing the number of times I pumped in a day and power pumping. My son will be 11 weeks on Friday and I'm starting to feel like I can keep this up a while longer after wanting to give up so many times.
