Ok...so even though I know there are alot of websites promoting the Nub Theory, I always wondered if it was just another one of those "old wives tales" kind of things. I had my ultrasound today and the technician told me that it is in fact true, and that if I had been only 3 days farther along she could have given me a definite answer on gender! HOW COOL! So ladies...even if YOUR tech won't tell you gender, ask for a good nub shot/profile so that the experts on BnB (lol ) can tell you the sex of your baby! P.S. My tech said she couldn't give me a definite answer because I was still 3 days away from the 12 week mark but as long as the nub angle didn't change in the next few days I would be having a girl So excited!
