Slow growth 😭😭

I was diagnosed with gestational diabetes from the glucose tolerance test which has led to growth scans. I had my first growth scan a month ago and everything was fine. Went today for my next one (33+5) and they said her growth has slowed. I’ve got to go back for a Doppler scan next week and a growth scan the week following that. I was on my own at my appointment (husband is in the military) and I feel like I’ve not asked enough questions. I see my community midwife on Friday and wondered if there was anything anyone could think of to ask?

They’ve said if her slow growth continues, I could deliver early. I feel like I’ve failed my little girl, what have I done wrong? 😭😭
