Tammy,
I'm so very sorry for the tragedy you've suffered. There's not much worse in this world than the loss of a baby or child, whatever age or stage of pregnancy, and my heart goes out to you and your husband.
Stable BG control IS acheivable providing you are on the correct insulin and insulin regime for you. Some types of insulin don't suit some people, and similarly multiple injection regimes don't suit others. I found after nearly 20 years of battling control on various insulins, that animal insulin was best for me. Others on this forum have found an insulin pump best for them. There's a section on this forum dedicated to insulin pumps, which might interest you.
You must speak to your diabetes care team and see what can be done to improved your BG control. Has your doctor given you any advice as yet?
take care, and welcome to the forum
