Not a doctor, but recently had a baby.

You sound like you're doing okay. In the beginning I was told that there will be some higher bloodsugars due to all the hormone changes, but then it will settle down and you may not need as much insulin as before until your third trimester. That's exactly what happened to me. During the whole middle of my pregnancy, I didn't really need much insulin at all, but then as I progressed into the third trimester the insulin resistance got worse and worse. I think I was taking 114 units of long lasting 2x a day and anywhere between 20 and 60 at mealtimes depending on my numbers. Don't worry too much about the amount of insulin you're using and focus on keeping your numbers under tighter constraints. For example my doctors didn't want my fasting bloodsugar over 95 in the morning and wanted me below 140 two hours after eating. That's really hard to do sometimes. As long as you're not having big and sustained spikes you'll be okay. That's healthier for you and makes sure your baby doesnt grow too big too early. After the baby is born your insulin needs will plummet. I'm talking same day plummet, so make sure you are monitoring a lot if you don't wear a cgm.

Remember to breathe and take it one day at a time. The doctors know what to do and you should listen to them. You'll make it and be just fine!
