Thanks everyone.

I've found some posts around the internet suggesting this has happened to a few others and their results were singleton pregnancies. I've pretty much convinced myself it is just one as I don't feel like I'm carrying twins but I guess I'll have to wait till Monday to get the confirmation either way.

Whatever happens, I'll be finding out the sex of the baby which is exciting as I have all girls and am hoping for a boy.

I will update you all on Monday.
