What if?

We'd decided after the whole ultrasound debacle we went through before, that we were done with ultrasounds. We know we're having a girl now, and we're done looking. At least I thought. But now out of nowhere I'm starting to get really anxious and nervous that maybe they missed something at that last ultrasound. Yes, the hour-long ultrasound that included me, both moms, an ultrasound tech and a trainee. I know any one of us would have seen something between those legs as many times as I had her check, but I'm still thinking what if?? They say that after 24 weeks gestation it's hard to tell gender anymore because the baby starts running out of room and gets more balled up in there. So my window of time to get one last look is shrinking daily! Yesterday I emailed the place that told us it was a boy to inform them it was really a girl. I'm hoping they email me back and say "come on in for free!" Still waiting. I'm just thinking about all of those horror stories where the parents planned for a girl and out came a baby boy on the big day! Think of all the weeks we could have been prepping. Yep, I think I might need one more ultrasound to set my mind at ease. I hope I won't (but know that I will) be this neurotic the rest of this poor child's life.
