HI
@BlueBerry11 and wishing you luck for your pregnancy journey.
My advice is quite dated (my kids are 32 and 28 and my pregnancies were pre cgm and pre pumps).
However it sounds like you are doing all the right things to minimise the chance of complications. It seems to me that diabetic pregnancies are a bit of a numbers game. Poor control worsens the chances of complications, but enough people have complications/miscarriages etc that if the worst happens you'd never know whether it was caused by the diabetes or would just have happened anyway.
Anyway, female T1s have been having successful pregnancies for the last century, it's just that the outcomes are so much better now. (My T1 mum had 3 pre glucometer pregnancies in the late 1950s and early 60s, and the first resulted in a stillborn infant, quite likely because she got pregnant way too soon after a late T1 diagnosis via DKA. Her deliveries were all in a London teaching hospital, despite living in Hampshire.) My two babies were fine but I had a fairly grim time as without a cgm I had some serious hypos. Given access to a cgm I would probably have gone for a third pregnancy.
So you have a pump, a cgm and (presumably) good access to a diabetic team. I think you are in a good place for planning a pregnancy and I wish you every luck for it, though I hope and expect that you won't need any luck. Modern technology is on your side. And (my opinion only, I'm not a doctor) you don't have to have perfect bgs throughout pregnancy, just do the best you can.
