Thanks for your query.
I hope you checked for a pregnancy
when your periods were delayed, as if you are pregnant, the progesterone tablets
would not work.
Otherwise in a normal scenario, you should have your periods within a day or two , and maximum within 5 - 7 days.
I hope you took the medication under proper supervision , in the correct dosage and manner.
If you fail to have your periods within a week, then please consult a gynecologist.
