I was asked to post an update so here it goes! I started posting here at 19, while a sophomore in college. I was using a medtronic 522 pump and the medtronic sof sensor at that time. I am now 23, married, and in my second year of medical school. I'm a MD/PhD student so have about 4 years to go after this one (at which point I will have been in school for 25 years!). I am currently using a medtronic 523 pump and dexcom G5. I switched back to the medtronic pump for my pregnancy because I found it the most reliable in terms of not stopping insulin delivery for occlusions or random alarms. I'm now 29 weeks pregnant. Overall it has been extremely manageable in terms of diabetes but less so in terms of my somewhat newly dx'd hypothyroidism which has been proving quite difficult to find the correct dose for. My pre pregnancy A1C was 5.5 and during pregnancy it has been around 5.1-5.3. My personal goal is under 5.5 and my doctor's goal is under 6. I'm using about 3x as much insulin at this point as I was before pregnancy but overall with basal adjustments every few days I am able to maintain an average of around 105. I do expect my insulin usage to continue to rise though-- I am quickly depleting my stock of insulin. I use dexcom clarity on a daily basis and that along with the dexcom has probably been the most helpful pregnancy tool for me. Currently I have urine tests, blood tests, and an ultrasound every 2 weeks but that will soon increase to weekly. Fortunately, the outpatient clinics are attached to the medical school campus so it is very convenient and I live a 10 minute walk from the hospital so overall I am very lucky in terms of managing all the testing. Pre pregnancy, I did set up a pregnancy planning appointment with a high risk OB (which I ended up showing up already pregnant to) but they really had minimal concerns regarding my diabetes after seeing my blood work and significantly more concerns that I am an Ashkenazi Jew (my husband is not) with a family history of tay sachs. So I ended up with quite a few genetic counseling appointments early on and had CVS at 10 weeks and my diabetes kind of took the back seat for my first trimester. I think that is it in terms of pregnancy. I will most likely have a scheduled C-section around 38 weeks unless something changes before then and we are very excited to meet our baby boy! If I could do this over, I would have set up a medical team in advance of my pregnancy. We were expecting much more difficulty due to my past medical history so thought we would have more time but I ended up having tons of issues getting appointments with the various specialists at the correct time. Also, I would have stocked up on pump supplies and insulin ahead of time because I really have run through what I thought was a huge back up supply.
