Diabetic and Pregnant?

Jessica
I'm a type 1 diabetic and currently 21w5d pregnant with my first baby. I'm on a tflex insulin pump but for the last few days my bgs have been all over the place. High then low then normal then extremely low. I'm at the point where I'm afraid to eat because I don't want my bgs being above 140. My a1c pre pregnancy was 8.1 and as soon as I found out I was pregnant (spontaneous not planned) I brought it down to 5.8 in just a few weeks. Baby is perfectly fine confirmed by fetal echo and 20 week anatomy scan but I'm just so paranoid that if my readings aren't perfect I'm putting my son at risk 😩 even if I'm above 125 I start freaking out. Anybody else here pregnant and diabetic? Type 1, type 2 or gestational?
