Problem a stupid question...?!

Amanda
I know its probably a stupid question and i will just need to wait for my scan.... But i keep having dreams i am having twins! There are twins in both sides of the family so it's constantly stated. I am very nauseous but not been sick and 9 weeks today... My first scan isnt until im 12weeks (living in the UK - only do scans at 12 &20w) but is there any other tell tale signs that your likely to be carrying twins?  Thanks!
