Thnak you everyone for the support and lovely messages. Sadly this seems not meant to be. Spent the night with bleeding and bad pain, and am very clearly miscarrying now. Will be having a D and C tomorrow.
The obstetrican offered to arrange an ultrasound today, but I just can't do it again, with two previous occasions of the ultrasound person turning to me and saying "I'm very sorry...". He therefore says he will do an ultrasound when I am on the table, just to be 100% sure the pregnancy is lost before he goes ahead, but he and I both agree that there is really no hope. He says that at the HCG level I had on Monday we really should have seen a heartbeat, and so he was not very hopeful then, but did not want to tell me that just in case.
I am of course very upset but I will get through this. Thank you so much everyone. I hope you all have better luck and I wish you all lots of happiness.
Nicola
