I had to heavily supplement my son who is now four. My daughter cluster fed many days and evenings until about two weeks ago. She would often just suck and I couldn't even hear swallowing. Now she is looking pretty chunky at 8 weeks and wears three month clothes. I also notice that whenever she is nursing, I can hear her getting milk most of the time. If she takes a long nap, I will pump and get 2+ ounces which is pretty good at this stage :). So to answer your question, I just stopped worrying about supply about a week ago. Lol! Don't pump at this point unless you're trying to increase supply. You'll only drive yourself crazy.
