Well I am currently 6 1/2 months pregnant. So far I have not developed diabetes or high blood pressure nor am I retaining any water. There has been a span of 10 years between my pregnancies and about 80lbs weight difference. With my first pregnancy I was young and healthy weighing in at about 140 at my son's birth. It looks like now I will be close to 230 at this birth and I'm ten years older and not in the best off shape obviously.
I know that I can't lose weight but I need to stay healthy and get into better habits after the baby is born or my weight will rocket back up past my pregnancy weight. I need to take active steps to avoid the post partum depression that I had after my first son because if I don't I will stagnate and the weight will go up.
I've taken up excercise, light to moderate daily, and added much more fruits and veggies to my diet. Which means I fill up less on bad carbs. (Can't break the bagel for breakfast though!)
