numbers climbing all day - no nadir!

[Mouse & Me]

Mouse's numbers have me puzzled. Started with a good number, then climbed all day, no nadir, as if she didn't have insulin at all.
Has anyone else had days like this?
I don't intend to go to bed yet until I get another reading, probably midnight.

My guess is she went lower last night than she is used to (hence the green start) and is slowly building up a bounce. I expect your next test will also be higher. And yes, I've seen cycles like this.
