Yesterday I had my appt for down syndrome and they tech said she is 80% sure I m having a boy! I was upset because I really wanted a girl. I hope it doesn't change later since I finally came around to the idea of having a boy. Do you thing it will change ??top photo profile of baby. Middlephoto baby standing in head the whole time.
