My son never had his hand there during an ultrasound and I have gone and paid for ultrasounds before so maybe you can look into that and find out what you're having :) Good luck!
I always did the 3D ultrasounds when I was 26-28 weeks, just for fun, and to also give us a definite answer on boy/girl!
And I agree with evthing4reason!
you don't need to explain anything to anyone....just say "we don't know yet" and leave it at that
My son never had his hand down there during ultrasounds. But I agree with mamaofone...I'm not sure where you live, but in most areas there are places you can go to get a non-medical ultrasound. And they are pretty accurate when they tell you the sex. There's one near me called Fetal Focus, and an ultrasound is only $75 or something like that, and they say if they can't tell the sex, the next ultrasound is free. I really hope you get your boy! (I'm hoping for a boy this time, too...boys are so much fun!)

I wish I could tell you....But really it could go both ways....If your dr. wont send you for another u/s, have you thought about doing a 3d/4d u/s? They are really Cool! I have TWO boys and they didnt do this in there u/s's......But I really HOPE you get your little boy!
