so when I went to my apt they told me my baby is 15 oz. After I thought about that...I was thinking maybe that sounded kind of high...21 weeks pregnant and almost 1 pound already!! After finding a cool site about average fetus weights...it looks just like with previous ultrasounds...my baby's weight is perfect for a 22 week baby. So...15 oz is right for 22 week. For 21 weeks the average weight is 12 oz. 2 babies ago, my Ella was induced at 36 weeks and 5 days because of my cholestasis. She weighed 7 lb 8 oz and the nurse said she looked like a 40 weeker in EVERY way!! Cant wait to watch this baby grow over the months!
