I'm not sure if this is what JenVose was getting at, and I will try to avoid being too graphic, but I will say that right around 36 weeks the downward trend in baby's position made it essentially impossible for my body to digest my food as thoroughly as before. Not just cramping the stomach but obstructing the whole digestive tract at times, and the results when I go to the bathroom are undeniable. (The midwife says this is totally normal for where I'm at.) So I KNOW I am eating more but the pace of weight gain (or lack there of) has not changed. The amount of nutrients we are extracting from our food has gone down, so the volume of food has to go up to compensate.
