Hi Danni, my last u/s was 20weeks and I was told it was a girl(99.9%) and I haven't had any other u/s since and I am due in 8 days.
I am worried that she is a he and has grown little boy bits since last scan lol.
I think it is normal to be worried especially when you have been told the sex beforehand as they can sometimes get it wrong thats why I am not setting my hopes on a girl just on having a healthy baby.

All the best
Michelle
