I opted for the NT and we had that this morning. The heartbeat was very strong (176) and the baby was wiggling and looked great! The nuchal measurement was well within normal limits. The placenta was attached on the right side, I think, so maybe another boy? But the HB old wives' tale says girl, so who knows?
It was hilarious because it was a full bladder test, so I drank the amount of water at the time they told me. Well, she put the probe on my belly and it lasted all of 11 seconds before she told me my bladder was TOO full and I had to go empty it out a bit.
Then we told our 3.5 year old today. I thought he'd be a little more excited considering he has been asking for a baby brother/baby sister for at least 6 months, but his exact reaction was "But I want the baby to be in my belly!"
