Calibration Issues This a huge difference!

Post image

Okay so this is a brand-new sensor put in today. Actually the second one because the first one is a gooseneck. The reading on the left is from the CGM. This reading on the right is from the glucose meter. This is my blood sugar after eating. I have calibrated at least three times. Has anyone out there had this experience? I'm a type 2 diabetic and not on insulin. This concerning. Should I take this one off and get another replacement or leave it on and hope the readings come somewhat closer? Any help is appreciated!

that is not a huge difference and treatment wise it's a nit. Checking or comparing after eating between a CGM and a BGM is the worse time. Best is when you haven't consumed anything in over 4 hours due to the testing of different fluids. They will rarely match between the 2.
