Thanks to everyone who replied, it's so nice to have such supportive people around who can give suggestions (or at least help you calm down). I've been trying to just relax and assume it's nothing serious, although I know it's not that I didn't pay because we don't have to pay for appointments here in Canada...so we'll have to see what happens. I'm going to call them tomorrow and I'll keep you guys posted. Thanks again, it really means a lot Kelly
