Heard the baby's heart beat!

BeckyFedora

Hi, all,

I'm about 11 weeks, 5 days, and we heard the baby's heart beat for the first time! It was 166 beats per minute. We go for the first ultrasound on Friday (5/25) when I'll be about 12 weeks, 2 days. I'm so anxious to see if I really am that far along. 

Has anyone's estimated due date changed drastically based on your first ultrasound? I would hate to think I'm at 12 weeks, but be told I'm only at 10 weeks (for example). 

Thanks in advance,

Becky
