High A1C. Consistent “normal” blood sugar?

High A1C consistent low blood sugar?

So, i am 4 months pregnant and recently found out from getting labs done about a week ago that i have pre-existing type two diabetes not gestational. My A1C was 7.6. and from all my doctors visits in the past 3 months, I’ve probably gotten my blood sugar checked 6 times. The nurses told me that my blood sugar range has been in the 70s and yesterday was 85. I’m new to all of this so I’m just confused how my A1c doesn’t compare to my blood sugar levels? or does it?
