Prediabetes and pregnancy

I’ve been so depressed and stressed. I’m 12 weeks and 4 days. I’ve been taking my blood sugar glucose. This morning (fasting) it was 106 when it should be 90 or less. But after breakfast, it’s 108, which is good because it looks like I did good. But I’m sitting here so worrried and so cautious about everything. Last night before I went to bed it was 126 when it should be 120 or below. Im gonna try again today. I hope I have better luck. Im so scared. Will anything horrible happen to my baby? This is my rainbow baby. I just want to cry.
