Have I kept you all waiting in suspense for long enough now? 
Well, the results are in! I had my scan on Tuesday morning, and it is a GIRL !!!!!!
I cant believe it, I actually burst into tears when the sonographer said it was a girl. It was almost an instant response from her, she said, "oh thats a girl" and then she spent a while getting other angles and each time she said "yep, its still a girl"! I am so thrilled, I am in a state of shock!
Thank you all for all your thoughts and good wishes, let me assure you, they were all in my mind as I waited for my scan!
