Thank you everyone for all your kind words...either here or email. I really appreciated all your stories and your hopefulness.
I've decided to wait for another scan on Tuesday, when I'll be 7w6d. If by then the fetal pole hasn't grown and there is no heartbeat, I will have to face facts that this pregnancy is not viable. But right now I can't do that. We've been progressing along "as normal"...just one week behind.
I can't get my RE's negative words out of my head though today. Every little twinge I'm feeling has me wondering "Is this it?" and running to the bathroom for a TP check. Each time, nothing. Thank goodness. I know I need to remain calm and try to stay positive. It's just very hard to do.
I can't believe this is dragging out so long without any answers. I wouldn't wish this on my worst enemy.
