I would only worry about a rising number test if you are shooting earlier than +12, or if the # is below 150. Nothing wrong with doing one otherwise, but generally at +12 it's not a big issue, unless you had something like an inverse curve that cycle.
I'd be inclined to raise the dose a little, at least a fat .6 or maybe go to 0.7, but as long as ketones are negative and she is feeling better I don't think there's a huge rush. Tonights PS is pretty good, so you could see where she is by tomorrow night, and if you aren't seeing green nadirs, then raise a little. [ETA: Never mind! Looks like this dose is good for the moment.]
