This is my first week using a CGM and I went swimming with my son today at the lake. We were in the water a couple hours so I know it didn’t get any readings. It’s been 5 hours and although the mobile app is now displaying readings it is not even close to my meter… 100 points off. Anyone had any similar experiences? Any advice? It’s only been on 4 days so I would hate to switch out the sensor already! I was careful not to bump it, etc.
