I had a bit of a lightbulb moment during my 12 week scan and said that surely the heartrate would go up and down depending on how active the baby had been/was when it was measured, just like ours does... and the dr doing the ultrasound looked at me as if to say, "Well, duh." and nodded.

I guess in the end it's always 50/50 either way, right? I really hope you get at least one boy
