Just wanted to post this incase someone in the future does a search...
I think I ran into my problems due to reducing the speed or setting on the pump from high to low before dropping session length or dropping more sessions in a day.
It makes sense as they say the pump does not effectively drain the breast as the baby does. So reducing the speed setting was a big mistake for me.
So for now, I will turn up the volume and hope all stabilizes over the weekend.
And thanks for your suggestions!
