Satya
I am so sorry for what you are going through. I really hoped this was your sticky baby.
I cant imagine how devistated you are. How long until your lap? I would definately follow your hcg back to zero at least then you know what your body is doing.
Take care and dont push yourself to hard at work.
Here is a little poem my mum gave me.

Angel baby, when you tiptoed into my life,
I knew it was only for a while,
And just the though of you, my darling, was
enough to make me smile,
When the angels came for you, I could hardly bear for us to part,
But I knew they would keep you safe,
forever loved, and within my heart!
