I work overnight at a hotel on the weekends so I usually am asleep during most of the day on Saturday and Sunday. I took my meds and also had a small high carb, low calorie meal from a fast food place. I just woke up and checked my blood sugar and was ecstatic when I saw my blood sugar was at 88! But then I thought about it and concluded that it didn't make sense that my blood sugar was so low considering no physical activity and a high carb meal. So I checked it two more times in a span of ten minutes and it went up each time. Here is my meter record: https://imgur.com/geW0lQA Is this normal BG behavior? Or might there be something wrong with my meter?

*Edit: Just to add, two of the readings came from the same finger. The last reading came from a different finger.
