35 weeks and raised amniotic fluid

Shannon
Has anyone hit 35 weeks and the amniotic fluid has raised from 6 to 8? 
The doctor said it could be because he's moved and so I have to have another scan in 2 weeks but I'm worried as its not something I've come across reading other people's stories and searching for topics unless I'm not looking in the right places.
Any information would be appreciatedXx
