I've had problems with 2 new sensors since yesterday. This, the third, didn't break down for 4 hours, but all readings were at or below 3.5mmol/L. Then it read 'reading below range', marked LO, showing a further downturn. I don't know what its lowest reading is. Has anyone experienced this? I'm T2 on pills, so don't expect hypos, but otoh, I'm taking pills that were prescribed when my diabetes was uncontrolled. Now well controlled. I didn't take my medis today out of an abundance of caution. Of course, it could be the Libre acting up, but this seems very odd.
