Yeah, I had it.
Even though I followed the diet, my blood sugars were still borderline/high, so they put me on a pill that lowered it - it was a once a day thing.
The major problem with it though was that it was one of the medicines that make you sensitive to sunlight, so you go outside and get exhausted because your pregnant and have this medicine that makes you overly sensitive to sunlight.
The hardest part for me was counting the carbs and making sure you eat properly- especially when the cravings you are having are for things that aren't low in carbs!
I had a c-section, but that was because he couldn't get into the right position. Every time I went to the doctor's, he was in a different position on the ultrasound.
Oh - because my gestational diabetes had to be controlled with medicine, my doc had me do non-stress tests at the hospital to make sure that everything was going well because I was "a little more high risk" because of the meds. Which is how I knew he was in different positions -
I forget what they were worried about, but it was mainly because they wanted to make sure that he didn't grow too much too fast because with gestational diabetes you run the risk of having big babies/having other complications.
(But then they get concerned if you aren't gaining too much weight too...which happened to me because of the low carb diet)
So, I had to go to the my OB's office and the hospital weekly for check-ups for that last month, but I think that's more of an exception rather than the rule.
My son was exactly 7 lbs. The docs and I were both happy that he wasn't a "big baby."
That was my experience -
I hope it helps.
