I stopped my birth control in February.  While on it, my period was regular (would always start the same day).  Well the day I would have started normally has come and gone, and I am now 2 days late.  However I know my periods would be different after stopping it.  Should I test after a week just to be sure?  I'm assuming the odds are that I just didn't ovulate this month.  But kinda feel like I should test just to be sure.  Thanks!
