I had the cab driver drop me off at the convention center and after paying FIFTY DOLLARS (!!) for that ride, I RAN into the mothers room at the conference. I immediately plugged in. Started pumping. And….very…little…milk. NOOOO! It was like the whole pump was on super low power and I just could not get it to have enough pressure. THE MEMBRANES WERE NOT THE PROBLEM. My pump was just broken. I was ALMOST in tears. My talk started in 10 minutes. I didn’t know what to do. I was 100% CERTAIN I would be leaking as I got up on stage to present to the room of 200+ people on the talk that I had hoped to have the morning to prepare for but clearly had other things to worry about.
