Thanks @Corbes and everyone else who responded,
The clinic just rang and confirmed my HCG is now under 5. They do not want me to do any more BT's as a reading of 5 or under denotes 'not pregnant' in their books. They said my cycle should come back soon now, most probably in the coming week or so. It is 4 weeks to the day since the D&C so it took a long while for my HCG to come down. That being said, it was 45,000 at one point so it had a long way to drop I suppose.
In some ways I am glad it's all over. No more BT's for now, so I get a couple of months to get myself healthy and prepare for what comes next, whatever that may be.
On the other hand, I am a little bit sad today. The last remaining bit of Blossom has now gone and I doubt I will ever get over that.
May I have some chocolate cake and ice-cream too please, while I have a little cry tonight about what might have been?
As for the neighbour, she has still not come back. The dog and the cat disappeared last Monday and I haven't seen any of them since. I am quietly wondering if she has done a moonlight flit - packed up and left under the cover of darkness.
