Oh hon you poor thing!!!! I know its hard, but try not to focus on something that may or may not be accurate ok? Until you know the final results, please try to relax for your little bubba's sake.
Take it easy, and I have all fingers and toes crossed here for you that everything is going to be ok. I'm sure it is, because YOU feel that there is nothing wrong. That beats any test in my book.
And to your future MIL - pffft.... get lost ya dumb mole....
(see I can be supportive!! )
Let us know how you go
