Your body will try to do everything that it can to produce healthy kids. Not saying you COULDN"T get pregnant with a high A1c, but it's challenging. Your body is more likely to have a condition called PCOS with a higher A1c. I was having severe insulin absorption issues even before my first pregnancy, so I am a type 1 on lots of injections, plus Metformin pills to help me absorb the insulin I inject. Metformin also is known to increase fertility.
Be careful: I know a fellow type 1 who unexpectedly got pregnant when she wasn't ready. Her A1c was over 10% at conception and she brought it down below 8% by the end of pregnancy. However, the doctors believe that due to her elevated A1c, her daughter was born with a hole in her heart.
The high risk team in my area suggests an A1c of at LEAST below 8% before conception. They state that an A1c below 7% will lower the birth defect risk to that of a normal woman... only IF you can get your A1c leveled out without highs and lows, as steady of a line for daily glucose levels as you can (fasting 60-90, 1 hour post prandial below 180, 2 hour post prandial 120).
It's a lot of work, but like you said, you don't want your baby to enter the world with anything less than a normal start.
So much luck and patience to you and your husband. It takes a lot of perseverance to get that A1c down. Then, the 9 months of pregnancy are extremely long and difficult.
I wake once or twice every night to check my glucose and correct. I test about 12 times per day. I limit my carbs to 30-45g per DAY to maintain my glucose fluxuations (I have severe insulin absorption issues and carbohydrate sensitivity). I inject about 15 shots per day. I exercise daily. This is my 2nd successful pregnancy at 18 weeks. We lost our first pregnancy and I also have a one year old daughter. When I was pregnant with my daughter, I was keeping such tight control that I went into 10 insulin shock comas. Then, I delivered with pre eclampsia, which diabetics are more prone to developing. It ain't no walk in the park. haha. But, it can't be too bad cuz I'm crazy enough to do it again, willingly, right?
Good luck to you. Keep asking questions and we will try our best to help you through. There are a lot of really good conversations in this birth club from last year. This group was really active last summer when I was pregnant with my daughter. Lots of great advice and answers from last year's posts. People don't seem to be as active with this year's pregnancies.
