Polyhydramnios - excessive amniotic fluid

Hi,
Went in for a 'positional' scan yesterday and though everything with baby was normal they have found my amniotic fluid are slightly higher than normal. The specialists appointment is scheduled for tomorrow and today I am trying keep my thoughts positive.

Has anyone here had a diagnosis of polyhydramnios this late in their pregnancy? What was your experience? My MW thinks I may need to be induced so that is another thing I may have to get my head around.

Thanks
