When to test?

I just went off continuous birth control a few months ago, so I am unsure what a "normal" cycle for me is, or if I even have a normal cycle. We have literally only had sex twice on the supposed ovulation days, (but again since I don't know my cycle I'm not even sure if those are correct.)  If I were on a 28 day cycle I would be a week late tomorrow, but I am otherwise having no symptoms of pregnancy. 
I was thinking i would give it a few more days before taking a test but was wondering what you guys might think?
