Im 31 weeks pregnant and had a routine ob appointment today. My Dr. Told me that I am measuring good, and his heart rate is good, but due to my lack of weight gain she scheduled me for an ultrasound next week to check babies growth. Im quite distressed over this knowing that I shouldn't have another ultrasound at all, and my Dr. Wanting one worries me. How am I supposed to go a week with this sitting in my head?
