High A1C at 19weeks pregnant

Before finding out I was pregnant my a1c was 9.3.. I've tried really hard to get it more controlled and last month it was 8.2. I am 19 weeks pregnant now. I am being seen by high risk and they are of course concerned with my numbers. I'm in auto mode on my Medtronic 670g most of the time with my target set between 80-90. I have had my anatomy scan at high risk and all looks good so far. Anybody have a high a1c throughout pregnancy and end up ok? Just stressing a lot (which doesn't help).
