Using the Nub Therory- please vote! 
This was taken abdominal at 11 weeks 2 days. I measured 11 weeks 6 days. 
We don't go to our gender scan unti 20 week (late August) and will find out along with friends and family at our gender reveal party in early September. 
Just thought I try this for fun. :) I CANT WAIT to know what I am having!!! 
Thanks for voting!
