Dexcom numbers way off after restating sensor

Hi guys

Anyone experience Dexcom G5 giving numbers that are WAY off after restarting a sensor? I wore this sensor for 7 days, numbers were pretty good. This morning, I restarted the sensor after it expired, and the numbers are way off, like reading 3.9 while I’m 8.8. Calibrated a few times. Any advice for this situation?

I know I can just put in a new sensor, but I’m trying to make them last as long as possible because I pay out of pocket.

Thanks!

Continue to do calibrations, 5-10 minutes, including using same value if bg is flat.
Also make sure you are well hydrated.

What location is it? If possible, exercise that area to get increased blood circulation.
