I saw "How do you do it" under pregnancy and was a little worried.
Seriously, not haven ever been pregnant I can't say but you might look into a CGMS system. Maybe for just the 9 months if insurance does ot cover it. With the CGMS you can see yourself going up or down and make the corrections before it goes way up or down. It has leveled out my control. I always had A1cs in the high 5s to low 6s but was having some high and lows. Now I catch them before it happens.
