How long after i stop taking progesterone suppositories will my period return?

2-5 days: If using Progesterone after ovulation, menstrual cycles will return after stopping the Progesterone in 2-5 days. That is, if there is not a pregnancy!

Few days.: If not pregnant, your period will start a few days after stopping progesterone.

Usually a few days: In infertility treatments, Progesterone suppositories are used to supplement or to replace natural progesteorne production (which may be inadequate in many types of treatment). Treatment with suppositories begins only after ovulation (release of an egg) has occurred, or after egg retrieval in ivf cycles. If you don't conceive, your period will usually begin 2-5 days after stopping treatment.

Within a week: Typically 2-7 days. If no period in 10-14 days see your doc for further testing. Good luck!
