1 Hour Glucose Test -- Failed and blaming myself for not getting the test done earlier

I am a FTM and 28 weeks today. I am already high risk due to Factor V and have been seeing a Maternal Fetal Medicine Doctor this entire time. I did my one hour glucose test today because I had an appointment around the same time. I got my results back and was at 148.

During my appointment I was told that baby girl was weighing big at 3lbs 3 ozs and is predicting to be over 9 lbs. At the time I laughed because my husband is a very tall broad man so I figured it was his genetics. But now that I know I may have GD, I am blaming myself that I have been putting her at risk this entire time and I did this to her.

How do I do better and how can I mentally move past this? This has already been a really hard pregnancy for me with all the blood thinner shots and just feel so broken.
