Hi guys, thanks for all your replies.

drbee, what you said is so true, I could get to the end of nine months and realise all I have done is worry. MY GP said to try to disassociate from the pregnancy, and not think about it at all, just go with whatever he says is happening. So I am trying hard to do that. Had a chat with my SIL last night, she just had a baby boy, eight weeks premature, after four miscarriages, and she said exactly the same thing, that there is no point in worrying because it won't stop something bad from happening if it is going to.

Good luck with your scan on Wednesday.
