I had my second ultrasound at 13 weeks and it never gets old! I wish I could see baby all the time, but until Feb (gender time) I gotta be patient 😓 Baby is measuring perfectly and due date July 7, 2016. I feel super emotional about everything again lately but little to no nausea but still wanting to power nap after little spurts of energy haha. Pretty sure I want to get a 3D/4D ultrasound a little later in second tri or beginning of third tri? Anyone know if you can choose when to go in or when you think the best time for me would be to see baby? Just trying to get some recommendations! Happy 2016 Preggies!
