Congratulations! Make an appointment with your endo now and ask him/her to recommend an OBGYN if you don't have one.
If you take ACE inhibitors (like Lisinopril) to prevent kidney problems, STOP THEM IMMEDIATELY. Not baby friendly. Your doctor can prescribe something different through the pregnancy.
I had first OBGYN appointment at 1 month and got to hear the baby's heartbeat! OBGNY handled my appointments and shared results with my endo so I wasn't always at the doctor. For first month he had me send my test results every week, but after realizing I knew what I was doing went back to normal appointments.
Your A1c is good. During pregnancy it's important to prevent both highs and lows. Use a CGM or test a lot to make corrections. If you don't use a pump, you may consider one. I wanted to have a non-diabetic A1c (below 5.5) so I aimed for a blood sugar of 80 and carb counted carefully. This might be too drastic; don't do it if you have any problems with lows.
I worked a full-time office job until the end. The pregnancy hormones made me feel great, but everyone is different. Expect to be really tired in first trimester. Try to get good sleep and the tiredness will pass as pregnancy progresses. By the 2nd trimester I did moms in motion water aerobics and yoga classes (see if your hospital has them). It felt good, helped my blood sugars, and was a great way to meet other expecting moms.
My son is 6 now, nondiabetic and healthy. I have no diabetes complications after 34 years with type 1. I'm not anything special (last A1c was 6.5, but after pregnancy I'm usually closer to a 6.7). Having a healthy pregnancy is totally possible for any diabetic woman. You'll do great.
