Regarding the medical team, it was more exhausting than anything else. So many appointments (I generally had 2-4 per week towards the end of the pregnancy). My endo was supportive and understanding and complimentary about what I was doing. The OBs were generally really well informed about T1D and understood I had good control so they were fine to let me self-manage and would just check in. The MFM (high risk doctor) was the one who seemed to lump all diabetics (regardless of type of level of control) together, which was frustrating. She was not willing to compromise on the timing of the induction - it had to be during week 38, no matter what.
Otherwise, I'd say managing the diabetes took more effort and a lot more guilt than it does outside of pregnancy. I feel like I'm constantly hyper-aware of my blood sugar and the effect it has on my state of mind and how my body feels. That's under normal conditions. Then, during pregnancy, every bg reading, every meal I have, if it goes out of that 60-140 range, comes racked with guilt about potential impacts on the baby. And then there's all the well-meaning questions from the medical team, my family, and others who know about my T1D. It was all just a lot. I'm glad that part is over, but again, thankfully, the pregnancy itself went smoothly. I can't quite imagine managing the diabetes AND a challenging pregnancy, although I can see that many women out there are doing just that successfully.
