Keto blood counts

I have been on the Keto diet for a month. I keep my carbs under 20. I have journaled on myfitnesspal to watch fats and proteins and carbs. I check my blood for ketosis at different times of the day a couple hrs after eating and it’s either .2 or .3. I’ve never gotten any higher. I read about the signs of being in ketosis. dry mouth and fatigue are present. not sure about the breath being different. my weight is pretty much staying the same. I have gained and lost the same 3-4# over the past month.  I’m wondering how to get the blood to .5 and above. the only dairy I consume is heavy whipping cream in my coffee in the morning and I only drink one cup (approx 12oz). I consume water all day. I sleep good. the only meds I take is a thyroid replacement. any suggestions are appreciated.
