Resurrecting an old thread to stop hijacking another! Picking up from here: Women's Health Wiki: How Has Your T1D Been Impacted By Different Female Life Stages? - #11 by RachelMaraii
I’m still in the midst of lots of research (will I ever not be?), but my husband and I have decided we’re gonna go for it. 
For now I’m in the six month preparation period, recommended by Pregnancy with Type 1 Diabetes by Ginger Vieira and Jennifer C. Smith. It’s been a helpful book so far (~20% through), but I wish I had bought the second edition! The first edition has confusing typos. If anyone is considering reading it, I’d also highly recommend reading Think Like a Pancreas by Gary Scheiner first.
How is the six month prep going? OK I guess. 
I’ve narrowed my CGM range to 70 to 140. I have about 75% time in range, with a 6.2 GMI (my last A1C was 5.5%). Highs after eating and then subsequent lows are challenging though. I’m aiming for a 1-hour postprandial target of 140 and 2-hour target of 120… and that doesn’t happen often.
I’ve got a folder full of Dexcom G7 meal screenshots to try to nail down pre-bolus timing. It is a struggle!! I can see why T1Ds would go pretty low carb for pregnancy… No matter how early I bolus so far (15-30 minutes, sometimes even 45 minutes if not already in target), if I have refined pasta or fruit or other carbs in my meal, then my 1-hour reading gets up to 180-200 and my 2-hour reading is 140. If I just drink a protein shake or something, I can easily stay in the 140/120 post-prandial range. But I love cooking and food, and that includes carbs. 
Any tips for pre-bolus timing?? I’m working on nailing the extended bolus too. Or is lower carb the easiest way to go to achieve those goals? Any recommendations for vegetarian/pescetarian low-carb recipe blogs or cookbooks? I have a friend (who I mentioned in the previous thread – now with a beautiful one-year-old!) who has tried all the keto desserts, so I have a resource for those. I know I need to do some basal, carb ratio, and correction ratio testing too.
My previous endo has retired, so I’m seeing a new endo in the same office. So far so good. I didn’t bring up pregnancy plans yet, since I’ve only had the new patient appointment. I’ll need to ask about her own guidelines in December. I’ll also plan to ask her about Gvoke.
My CDE mentioned that Tandem is supposed to offer a custom Control-IQ target BG in the next year or so, specifically because of stricter pregnancy targets. I’m hoping that update will release soon! I am so grateful for the basically straight line I get overnight with Control-IQ.
I also downloaded Sugarmate yesterday!! Finally available for Android. 
So far I like the “extended drop” and “extended rise” alerts. And I think it will comfort my husband to have the phone call feature for overnight lows once hopefully pregnant.
Any other favorite tools or methods to achieve that stricter target BG range? Thanks in advance!
