20 Week Ultrasound!

Hannah

We had our 20 weeks anatomy scan today! Baby was measuring at about 19w3d even though I'm calculating 20w1d. It's under a 10 day difference so they are keeping my due date at 2/28/19. Heart Rate was 149 and baby is about 12 to 13 oz. Little one was head down and curled up in a little ball most of the time and likes to have its hands and arms up by its head. Any guesses on gender?
