Progesterone: If you are "five days late" and have had sexual relations during your last cycle, get a serum HCG test to be certain you are not pregnant. Norethisrone will not prevent your period at this point in your cycle. If the HCG test is negative, you may just have not ovulated this cycle, and stress is the most common cause of delayed ovulation if you are not pregnant.
