This sounds fun! I would love a guess...as it's something I'm not planning to find out unless my midwife ends up suggesting an ultrasound for some other reason.
This is my first pregnancy, and my estimated due date is August 25th.
Here is a link to a photo of me at 12 weeks:http://i663.photobucket.com/albums/u...lly13weeks.jpg
No guess for me yet, are you unsure? I've had several people in the last week ask if I might be having twins - including my very connected grandmother who said "I think maybe you're having a boy AND a girl". Do you also get this same feeling?
