I am typing this with an 11-week-old in my arms.
I wore Omnipod and Navigator during my pregnancy (and beyond). I swear by the combo and wouldn’t have it any other way, but if I were you right now, I’d consider the Dexcom 7+. It will soon “sync” with the Omnipod - though perhaps not by the end of your pregnancy. (Omnipod isn’t currently integrating with any CGM, but has it in the works to sync w/ both Nav and Dex, Dex being 1st.) And Abbott has a temporary disruption in their Navigator manufacturing and isn’t taking new orders right now. D7+ is a great product and I think it’s exactly what you’re looking for.
My CGM helped me have a smooth pregnancy by helping curb highs and catch them on the rise, giving me trending data as my insulin needs changed weekly, and giving me my standard deviation and averages to share with my health team.
Insurance covers it as DME at my DME rate, like a pump and pump supplies.
It’s important to note though that you will still need to do finger-pricks. Interstitial glucose monitoring isn’t quite accurate and up-to-the-minute enough to base a bolus dosage on. I still test with most boluses and certainly did while pregnant and going for tight control. CGM is a supplement and not a replacement.
