18 weeks pregnant and have put on 4lbs this week alone on my home scale. Blood pressure 108/62, no visible swelling. Worried weight is going to start coming on quickly. I've been eating fairly healthy and drinking tons of water....can't lie though I've been eating a serving of chips everyday. Uhh. Is the weight gain jump happening to anyone else? What did you do to slow it down? I'm doing some form of movement everyday too whether it's waking or elliptical. I've gained 11 lbs so far and I'm 18 weeks. Was hoping not to gain more than 28-30 lbs total. Tips/suggestions plz!!!! I was on the very high end of normal weight range prior to getting pregnant
