If you are concerned it means pregnancy, go to the drugstore or the Dollar Store and pick up a pregnancy test, and test first thing tomorrow morning with concentrated urine.
Just depends. Do you believe that your cycle was just late or was there other factors that could have made it late? Is there a possibility you are pregnant? Have you had a history of ovarian cyst? These can cause a late menstrual.
But also as we get older out body changes. Your hormone levels change and your cycle can go through changes. So many things can factor into a late cycle. Even antibotics can cause a late cycle. Or changes in birth control.
Most of the time a late cycle isn't anything to worry about. I pray this response helps. May God bless you,
