Tina, I know this waiting for anything definitive is just awful. At this stage though you are borrowing sorrow from tomorrow. This could well be nothing serious. I am praying that is so. You know all the helpful advice to keep busy and try to think of other things. When I was in this position I also found a blue sleeping pill a must to get a good nights sleep to avoid over thinking everything.
Know that we are thinking of you and keeping our thoughts positive.
