Is my breast pump broken, or is my supply drying up?

I have a Medela Freestyle that I used with my first baby 6 years ago. It's been fine, up until the last week. This past Saturday, I was able to pump 3 ounces at a time. The past 4 days, I've only been able to pump a few drops. My LO is 2 weeks old. Is it worth buying a new pump, or is my milk just drying up?
