It will not be healthy if I gain weight because that will put me at obese. Currely 4 weeks pregnant with 6th. I do not want to be tired and feel lazy because of overly unhealthy weight gain. I am currently eating healthily and walking for exercise. I am 5'4" and 173 lbs so if I gain too much weight that puts me in the unhealthy zone . So for overweight and obese preggos can we go without gaining weight with the help of exercise and baby be healthy still? I never went this healthy route. Every pregnancy I end up gorging on food and gaining 70 lbs but this time I'm being careful. I'm in my 30s and with 4 kids and a dog I need to keep up with.
