Today was my first day of class (I'm at college )I was changing my site and I filled my resevoir. So I put my resevoir in the pump and it told me NO DELIVERY. So I took it out and it was completely EMPTY. How does all that insulin just get out of my pump? So than I did it all again, I filled the resevoir, everything, and it's saying all I have in their is 14 units?!?!?!? I should have closer to 100 (I only fill the resevoir to 50-100 units.) I don't know what it going on? I'm about to call mm. Help please???
