Know that you aren't the only one and just because you are diabetic does not doom a pregnancy. I have been diabetic since 16 being told I was type 1 then type 1.5.
I am currently entering the third trimester of my first pregnancy and apart from some emotional issues (which do effect my bg's) the pregnancy has gone well. If you only had to switch one medication you are lucky I got taken off of a few completely and had to change another.
Best advice I have is relax and talk to your diabetic team often. The others are right I have been dealing with my own insulin issues, the pregnancy causes you to need less sometimes and more others it isn't fun and makes me feel like I was just diagnosed again. Just know there is support out there and try to relax if you are concerned talk to you team. Some people are able to get pumps to help with the constantly changing needs with insulin while pregnant, something to look into
Good luck, keep us posted
and if you need to pm me we can share the ups and downs of diabetic pregnancies
