How did you lower your hbA1c for pregnancy?

Been t1 for 27 years and always had average control. My a1c sits around 7.2%/7.3%. I’ve recently started vyvanse for adhd and this so far has been making a huge impact with remembering to bolus, less binge eating and less anxiety around giving insulin but I don’t know how I’m possibly going to get it into 5’s and keep it there for a baby.

I’m on a tslim pump with cgm too 😊

Any tips??
