I appreciate your query.
You have not mentioned the dates of your last period, and the expected normal length of your regular menstrual cycles.
Normally, if you still have a week to go before the expected date of periods, you can start taking progesterone tablets
and continue taking them till you want to avoid your period.
After stopping them, you will have your period normally in 2 - 3 days, maximum within a week.
However, the period might be heavier than usual
Please fiddle with your menstrual cycle only if absolutely necessary.
There are various brands available in the market, for the correct dosage ( based on your body weight ) and time of starting them, please consult your gynecologist.
