Ellie, I know how you feel. I had my scan last week at 13 weeks and I was terrified. I had just lost a baby at 8 wks and found out at a scan that it had gone So I was so afraid of the scan even though I'd already seen a healthy baby at 9wks this time (after some very scary spotting). I had no indication that anything was wrong either but couldn't get the thought out of my head and then was even thinking that the fact I was so worried must mean something, maybe I subconciously knew it wasn't going to be ok. LOL, of course everything is perfect. I think it's kinda a way of protecting ourselves so that if something is wrong we will be prepared. I'm sure everything will be fine and once you see that little baby on the screen you will be so relieved and can just enjoying watching the little bub splash around in there, lol, it was the best thing ever once I realised it was in there and its heart was beating. Good luck, I will be thinking of you
