The thermometer that's actually in the water is probably more accurate (the stick-on has that glass barrier that can interfere with really precise readings).

Are you seeing any ulcerative areas (ie. pus, blood, redness) where the scales are missing?

If it's not constipation (it doesn't sound like it, due to the all-over bloat and the poo you described), then you could feed, but do so lightly. If she still has an appetite, this is good.
