Thankyou all for you support,
Shanti, I am really torn, the only appointment I can get we had to take the boys out of school. we dont have family to look after them so we have to take them. I dont want to take them into the scan ( they do know what is going on) so my DF has to stay with them. They will drive me there and bring me home but I will be in the scan on my own . I a wee bit scared but I have had one before many years ago.
