Sick and weirdly low numbers

Is it normal when you’re sick for your numbers to be extremely low?

I had norovirus. I was sick Saturday - Tuesday. When I’m sick, the only things I usually want is coke and plain chips. I wasn’t eating or drinking a ton but when I did have that, my numbers never went above 110.

Yesterday and today I had food that should have made my numbers rise but they still aren’t rising. I have been lucky this entire time and been able to tolerate more than others I’ve read about but this seems to good..

I have a CGM but have also been checking with finger pricks.

Baby is active and normal so I’m not super worried about my placenta failing yet. I do go to the doctor tomorrow but hearing from you guys is always helpful. I’m 31w 3d
