Ladies, please don't be this focused on your weight. As long as you're not just stuffing your face 24/7, and being healthy in general (which we all try especially hard to do during pregnancy), you are FINE. There is a huge weight prejudice out there during pregnancy, and they will tell you that anyone obese is not allowed to gain a single pound throughought, or at most 11 pounds total (that is what I read during mine as far as the accepted American standards for obese pregnant women. I hate that word, by the way.) They will tell you your child is more likely to need cesarean, which is also not a given. If you have good medical care and know what size the baby is expected to be, it can obviously be done. Women have eight, nine, ten pound babies vaginally routinely.
Eleven and twelve pounds are more rare, but you should be able to know going in what size to expect. Our doctor told us with our first that he SHOULD do an ultrasound before inducing because she measured 6 weeks ahead. He did not, and we had a horrible experience. Both of us nearly died getting her out. But she was over 12 pounds, and as it turns out I had GD and they didn't tell me about it. My point is you have the right to KNOW what you are getting into, and to DEMAND that they treat you well. Your body size does not make you any less pregnant than anyone else, or for some reason deserving of size prejudice or abuse.
This is a good article on the matter. https://www.midwiferytoday.com/articles/size_friendly.asp
Anyway, my point is that this is not the time to allow ANYONE to punish you for your weight. If you are not getting good care, please know that you have the right to change your doctor and do it! I wish to God I had done so with my first daughter. Sure, we'd have had a cesarean, but both would've been saved years of trauma. If your doctor isn't talking to you about your weight, don't ask. Seriously. If it is a problem they will tell you about it. My OB was amazing. I came in there nearly 500 pounds and he didn't bat a lash. Every OB in his practice (b/c you know, they make you do the rounds) was the same way. It was about my health and health of my LO. I didn't know people could be so nice. If you're not having that experience, no matter how late in your pregnancy, find an OB who will give it to you. The outcome will be best with someone who is focused on baby health and not mother size. Your experience will be better, and let's face it, a relaxed preggy mama is a good thing. Just my 2cts.
