Wedding rings

I picked up our wedding rings this lunchtime.  April's ring looks great and fits inside my ring quite easily, but my ring doesn't quite fit, it feels one or two sizes too small.  Doh!  It's not a problem as we can get it resized for free and it only takes a day but it would have been nice to squeeze it on.  As it stands i'm too scared.  The lady said my finger may go down in size in the cold so have taken it home anyway to see if that helps.  Otherwise it'll need to be size Z+1 or possibly even Z+2.  Yikes!
