Hi Katie. I agree with what everyone else said. When I was pregnant, I checked my sugars about 15x per day, including through the night. My mantra throughout pregnancy was "check and correct, check and correct."
I had a LOT of lows during my first and early second trimester. I used to eat a McFlurry when low, and an hour later I would STILL be low. It was annoying. I once passed out from one and my husband needed to use glucagon, which then made me extremely high for a few hours. But baby was fine, but it was a very scary time. Lows have little to no impact upon the baby (unless you go unconcious and stop breathing or something). And as long as you get your highs back to normal as soon as possible, they aren't anything to stress out too much over. It's the highs that go one for days and days that can negatively affect the baby.
Make sure you are taking prenatal vitamins now. Diabetics are more at risk to have a baby with spina bifida and taking a vitamin with folic acid greatly reduces that risk, as does avoiding highs.
My endo recommended an A1c of 7.0 before becoming pregnant so that's what I did. By the time I had my son, my A1c was down to 5.3 but that was due to daily lows.
Yes you do get to have lots of ultrasounds. I actually threw out some pics (like 20) because I had too many for the album. By the end of my third trimester, I was having appointments 2-3x's per week for OB, ultrasounds, NSTs or endo. While it's fun, it was also stressful because I kept waiting for them to tell me something was wrong. But they never did. That stress has been my one hesitation about having another baby - I think I need to wait a while until I forget! So I agree with Candace who said make sure you try to relax.
I was allowed to carry to 38.5 weeks. At that point I was on almost 3x the amount of insulin as I was pre-pregnancy. I opted for a C-section because of the high failure rate of inductions for diabetics (because we are being induced early and our bodies aren't always ready, plus they don't like to let us labour for too long - the failure rate is 50% for diabetics, and 30% for non-diabetics) and because I was having fluid loss.
When diabetics have babies, they babies blood sugars are monitored because they tend to go low (this is because they have been fighting the mom's higher blood sugars and once that blood supply is cut off, their own insulin over-production causes a drop). My son's sugar went low about 3 hours after he was born so we gave him formula and he was fixed right up. They continued to monitor it over 24 hours.
When diabetics breastfeed, their sugar tends to drop. Mine would drop as I was feeding him. Breastmilk is produced on a continuous basis and draws it's calories from the mom's body. There is no connection between a mother's blood sugar level and the sweetness of her milk. Sugar in the milk is lactose, and is produced by the cells of the breast and not drawn from the mother's blood. I only say this because I heard of a diabetic woman who stopped breastfeeding because she thought her milk was 'too sweet' due to her higher numbers and making her baby fat. So I consulted a doc about it and that's what I learned.
ISince having my son, I've gone on the pump. My sugars are in way better control now than they ever were, even when pregnant. If you have the option for a pump, I would recommend it.
Sorry for the novel. Hope this helps!
