Hannah • Pregnant with my first baby! Having a BOY 2*17*16 Hubby has a 5 year old little girl! So he gets his princess and his prince ❤
How long do I have to wait for the genetic testing results to be back? We find out what we are having and if everything is OK. They didn't tell me how long I go back the 25th will we know by then??
