I just wanted to post an update about my negative pregnancy tests.
I made arrangements to have an early scan at a private scan, and was fortunately able to get a scan today. I had an internal scan and sadly the sonographer was unable to confirm a pregnancy. There is a slight possibility that it is too early to spot a pregnancy and there is something in the womb that could have been, or could be, a pregnancy, but she could not confirm. She did stress that it is unlikely.
I have been advised to test again in a week if there is no bleeding, and if positive, to go back for a scan so that she can see if there have been any changes. She did look for an ectopic pregnancy and she could not see any sign.
Obviously as I had a positive test I am looking at the positive side, which is that I conceived naturally, having never done that before. I have removed my name from the list below as I suspect it is likely that I am no longer pregnant. You never know, I may be back, but I shall say goodbye for now. Good luck to you all, and I shall be looking forward to the birth announcements in December!
