Elevated levels of progesterone is what causes your period to stop, but hcg plays a role in that too, as it is the presence of hcg (from implanted embryo) that tells the corpus luteum to keep pumping out the progesterone after the normal luteal phase length. If there is no hcg detected the corpus luteum tapers down progesterone production after about 14 days and the endiometrial lining starts to break down when the progesterone no longer is present to support it.

Menstruation is triggered by a drop in estrogen and progesterone levels, which signals the shedding of the uterine lining. This drop in hormone levels occurs when an egg released during ovulation is not fertilized. The decrease in hormone levels causes the blood vessels in the uterus to constrict, leading to the shedding of the uterine lining, resulting in menstruation.
