Thanks for asking march ... Still in limbo sadly. The test on Sunday was the only one which was lightly positive, all clearer than clear since then, so whatever it was must have gone. Meanwhile 7 days overdue now and clearly going bonkers so booked to see doctors tomorrow. 
You know one of the awful things about this all is how we saw that test, it was just an "Oh, ok. Maybe." I feel like if even if we're ever lucky enough to have a pregnancy which sticks, we just won't ever get the joy other people do.
(Sorry, I know many people have it much worse than we do and don't mean to be overdramatic! Just feeling a bit sad generally.)
