CONGRATULATIONS!!!!!!!!!!!!
I'm currently at week 25 w/ my pregnancy and it IS a girl. I thought FOR SURE it was a boy, but for no real reason.
It's so exciting to see you this happy about your pregnancy! How touching...and it is great to hear that heart beat as a conformation of that little life inside of you. And if you think THAT was emotional...lol, wait 'till you SEE what you're hearing for the first time on that ultrasound monitor.
FYI- my little girls heart rate was 176 bpm at 8 weeks and 6 days.
