Hi,
I had my 12 week scan (I'm 13 and 6) and they told me that they could see some things that wouldn't normally be there. Firstly my yolk sack was still there (I didn't know what that was but they said it what the baby fed from before the placenta - it's normally gone by now) and secondly that my coelomic cavity (?! think it goes around my womb?) is bigger than normal.
They told me not to worry and said that everyone is different - it just might be like this for me - but I can't STOP worrying now!
Does anyone have any experience of this or any of the issues they pointed out?
