A question from dad/gender determination 99% girl??

You know, they say for everything it's only 99% sure. The pill isn't 100% effective either, and pregnancy tests aren't 100% accurate. I don't see why you'd doubt it. If they're really not sure, they'll tell you themselves. Unfortunately, I have to wait until my 20 weeks before I can go back to the OB-GYN for the gender, hoping they can see it.
