Week late

AF is a week late and it's never been this late before. I've been told it's probably just because I came off BC a couple months ago, but my first AF post-BC was completely normal and as scheduled. I'm not really having any symptoms other than a little bit of cramping last week before I was supposed to have started, and maybe a little nausea (but I might just be creating that in my head). Should I go ahead and test or wait it out a little longer in case the BC just threw things off?
