I agree if you think the pump is not working correctly, call tech support. They will have you do all kinds of checks to make sure the pump is functioning.
And just a side note. Over the years, this has happened many times. All of a sudden, insulin just doesn’t seem to work. I make some major adjustments that need to stay for a few weeks and than things work back down. Who knows, infection, hormones, weather. Can’t always find an answer but I push more insulin and sooner or later things start working back down again. The joys of diabetes. No rhyme or reason sometimes. But also long as you have changed infusion sets, and sites and insulin bottles, it just might be who knows. Calling the pump company such be first thing.
