Good news girls!!
I had a normal scan and another transvaginal scan and the specialist and his colleague said it was all fine. They looked at the baby from all kinds of angles but couldn't see anything wrong! They also put me back a week, relief is not the word! Back to work after lunch, hope not too many people come and stick their nose in and ask me what's wrong, hopefully they'll all be thinking about the weekend and nothing else.
Massive thanks for your kind words it really meant the world to me. Fingers crossed this is the end of the drama and I can enjoy being pregnant soon, not long till 15th March when I have my proper scan and transnuchal screening too.
