Here is a video of ours! I recorded the whole thing from start to finish so if you are interested as to what to expect you can see it there. A lot of doctors are different but the general stuff is the same.
At 4 minutes you can hear my shock when I find out its a girl because the whole time we thought it was a boy. At our 15 week appt doctor told us boy, DH is 1 of 4 boys and only has nephews. First girl in the family ever!
