Absolutely gutted

I had my 28 week midwife appointment yesterday. It was a different midwife to who I usually have, she was lovely. She said she had been looking at my record to familiarise herself with me and asked if I knew I failed my glucose test back at the start of Feb, which I didn’t. No one had contacted me. She was frustrated for me and added me to the diabetic team list. Later on I had a call from the team and they informed me I had also failed my glucose test back at the start of December and again no one had told me, not even my midwife. I feel failed by the system and that I could have been making better choices since December for myself and baby. Now I have a lot more appointments and growth scans I have to attend and check my bloods 4 times a day, I’m still in shock from it all and no one seems to be taking accountability for this mistake. This is my third and last pregnancy and I feel very low about this whole situation, I feel like it’s a sad ending to my pregnancy journey. This is just a rant, but if anyone had any advice or has/is dealing with GD I’d love to hear from you
