I have noticed something truly bizarre lately with respect to my CGMS accuracy.
For the last couple of months (I’ve been using sensors continuously during this pregnancy), my first 2-3 days with a sensor are crap in terms of accuracy. Not completely useless crap, but pretty unreliable crap.
Then, when Day 4 hits, and I restart my sensor, it’s almost like it magically becomes uber-reliable and fantastically accurate. For the next 3 days I’m in sensor heaven!
Then Day 7 hits and my transmitter needs a recharge (otherwise I get all kinds of Lost Sensor errors), so I recharge and restart….and still accurate!
The girl who used to have to remove sensors by Day 4 because they weren’t working anymore is now reluctantly removing (almost) perfectly functioning sensors on Day 7 or 8 because of skin irritation. (At that point I’m starting to get nervous about infection if there’s any sort of itchiness or redness.)
What is going on?! Is this a new pregnancy thing? Is this to do with the fact that I pinch up my skin on insertion now? Is this something new with the sensors? I’m totally lost for an explanation.
Now I just have to figure out how to improve on the accuracy during those first 1-3 days!
The funny thing is, Medtronic recommends only using the sensors for 3 days and then tossing them. Hmmm…..
