After taking progesterone for ten days, you will usually get your period within seven days of stopping the medication. Progesterone is used for various clinical reasons, for example, some people use progesterone during the luteal phase after ovulation in order to increase the rate of conception. Some people do not have a period for a long time and may use progesterone in order to have a period. In other cases, the endometrium develops thin during the luteal phase and progesterone can be used to increase the thickness of the endometrium to increase the volume of menstruation during the menstrual cycle. Therefore, the essence of using progesterone for various reasons is basically similar, mainly to enhance the function of the corpus luteum and support the endometrium, so it should be used for at least about ten days, preferably two weeks of progesterone, and after stopping the medication, withdrawal bleeding, or menstruation, usually occurs within a week’s range.
