Period over a week late

I had unprotected sex Jan 31-Feb 1st and I am over a week late. I do not know what to do and I checked my ovulation calander and I was supposed to ovulate Jan 27-31st and I am now late. I am on strict birth control that is specified to not have me be late at all; I have been tired or either staying up all hours of the night, craving food all the time (unusual because I take medication that makes me have a depressed appetite but now I still am starving and eating). I am also having tingly breasts, picking up weird and unusual smells that I do not pick up regularly.  Should I take a test now? Or wait?
