Hello all,

T2D using Dexcom g7 for 4-5 months now. Zero issues thus far. Tonight I changed my sensor and immediately did a calibration blood stick which was 95… 3 points off from the G7. Then it started to drop. All the way below 40. It actually said LOW instead of a number at one point. I did a second stick and was still in the 90’s. Used that second one as calibration too then ate dinner. After dinner I was still in the 50’s in the app and my stick was 160’s. What’s the deal here? Bad sensor? I know some say not to do a calibration as it’s not needed, but I typically do just one in the first 12 hours. I’ve never seen it doing this before.
