I am a mom. When I was pregnant there was no A1c testing, "control" was MIA - but that was before we had pumps or even mdi. My belly was huge because my baby was getting all of the nutrients I was consuming, so a short visit in the hospital to monitor and readjust the insulin dose and meet an endo who knew how to care for a pregnant T1. Keeping the bg in a managed range is way more important than trying to achieve a proper A1c. A T1 can get a normal A1c by having horrible control. Of course you will want to have your diabetes managed well but it does not have to be difficult. And yes, it is possible. Being pregnant was the beginning of gaining tight control in my life as a diabetic.
I did not have cravings, or morning sickness, or discomfort, or tiredness. I really had no troubles once the insulin regime was improved. I had an 8 - 5 job and rode a park and ride bus to get to work. Our bus was packed each day so many times I had to stand for the 45 minute ride. THAT was a bummer!
My kiddo decided to arrive early, and was delivered by c-section. Because she was premature she had to stay in the hospital for a short time, but that was okay since I was there too. My best tip is to tell you to keep your bg in the range you and your docs feel is safe and best for you. If you have a chance to find an OB who is experienced with pregnant diabetics that would be great. My own OB was recommended for a 'high risk' pregnancy and he was the one who then recommended the endo to help determine the insulin needs.
My kiddo has a kiddo now, and we are all healthy and happy. End of story :)
