"5 days before missed period"

So today would be my so called "5 days before missed period" but we aren't going to test. I want to, of course, but I can't see wasting the money. I will know in five days...or maybe more if I decide just to wait it out til Thursday just in case I ovulated late due to coming off of Ortho Evra. I am really nervous that I simply didn't ovulate this month. Time will only tell.
