1babysmom, I can totally relate. I've also gained about 30 lbs, feel huge and am worried about various things. There's a good chance I have gestational diabetes, but for some reason I've neglected to get tested. I was going to get it done earlier, but lost the lab slip, then the dr told me to wait until week 26... I'm having a really hard time eating properly. I have also gained as much as 45 pounds in the past. My babies were all under 9 lbs, but that's because I was always lucky enough to have them by 38 weeks.
I hope you're in the clear with GD!
GD isn't something I'm really concerned about, thankfully (I don't get tested, only have for 1 pregnancy- the one I gained the most on, actually-, and it's not something I've felt led to do this time either), but I still choose to watch my diet and, for the most part follow the carb. rec's. I also test my BGL's regularly. Now I know this isn't foolproof and that GD can still be present in women without appearing in the typical manner, but I rely heavily on intuition and prayer and neither has led me to feel like it's a concern. I DO know my eating habits aren't the healthiest though and I know I'm responsible for that.
But I've also always gone to 40+ weeks with each of my babies. (and the first was induced- AROM- and the 2nd and 3rd were castor oil babies, so who knows how long they would have taken otherwise!) My girls were 7lb'ers (but tiny and petite, just very lean), my boy was the big one, and all the boys in both my family and DH's were huge so I don't feel there is much that could have changed that. And he wasn't a "fat" baby by any means (like how you can look at a lot of big GD babies and just tell), he's just very lean and big boned (his measurements were larger from early on in the pregnancy)...basically a bigger, boyish version of his sisters. If anything I feel BETTER not having someone dictate my pregnancy (or try to find reasons for it) based on that, you know?
But going the full 40+ is also what stresses me out about gaining so much and being so uncomfortable, because I have all that extra time in there, and man, every day and the end is vicious!!!
