Hi there! I totally get your concern!! I, too, was unsure about switching to the pump after being well controlled using pens but relented about 20 weeks into my first pregnancy (I was 30 at the time, 34 now). Of course do what feels best for you, but two healthy babies later I am very happy I made the switch. Managing BG during pregnancy is FAR HARDER than I ever expected and even with outstanding endocrine care, I had to make adjustments weekly to keep within my target levels. Plus the pump makes adjusting insulin delivery throughout the day much easier (pregnancy hormones cause increased insulin resistance and since these hormones vary throughout the day, so will your insulin needs). Not that everything was super rosy- I often felt more “sick” because I was now wearing a visible indicator of my diabetes (most people didn’t know I had T1D prior to going on the pump) and had to answer A LOT more questions about diabetes, basically I became an unofficial diabetes ambassador, and then there’s the at times very annoying alerts when the reservoir gets low or its time to change the device (I use the pod). But the power it gave me to have safe, healthy pregnancies with no complications for me or my kiddos was absolutely worth it. With a good support team of diabetes educators and endocrinologists who specialize in diabetes during pregnancy, I had no trouble “adjusting” to the pump and, as I said before, when I first went on I was 20 weeks pregnant. If your docs aren’t supporting you now, ditch them and find specialists who will. Not all docs, even endocrinologists, understand how to manage the insulin craziness than accompanies pregnancy so find some who can. Sometimes your insurance company (if you have one- which I hope you do) can help you with this search.
Best of luck to you!!
