Thanks Emmy83.
Firstly, I am so so sorry that you have had such an awful and terrifying experience. I apologise whole heartedly if I have raised any emotions. I am truly sorry.
Secondly, I just want to give you a big hug and say thank you, finally I feel that someone is as concerned about this as me.
I have done a fair bit of research and have called my doc back this afternoon. They still don't know where bubba is living but because I am not showing any signs of danger (bleeding, no more spotting, pain etc), they think that waiting till Monday will be fine, but if any of this changes then to get to ER immediately. However if I am concerned they will do a lap for me straight away.

My HCG levels started rising slowly from my first bt.
14dpo - 40
16dpo - 70
19dpo - 290
6.5 weeks - 932
7.2 weeks - 1350
7.6 weeks - 2381

I had the scan at 3.30 yesterday afternoon and the sonographer actually asked if I definitely thought I was pregnant as there is no indication of it anywhere?
I am really frustrated about the whole thing to be honest and just want answers.
My problem when I first noticed all of this was that the clinic was closed over the xmas break and last week the scanning places were also closed!
I don't know if having another scan would pick up anything would it? Surely they would have seen signs of it yesterday. It was a pretty professional scanning place and it seemed pretty thorough.
I am scared to go in for surgery "just in case" IFKWIM. Am I trying to hold on to something that might not be there. But then part of me thinks what you mentioned about maybe losing a twin?
I think I am going to wait till Monday. I haven't had any brown spotting as such for almost a week. My CM however is between dark yellow and clear, which might not be right either.
Thank you again Emmy83, I will most certainly take your thoughts into seriousc considretaion.
