All women will experience vaginal bleeding, or the period, when their bodies reach a certain point of maturity. This bleeding will occur every 28-30 days and, from the end of the period until the middle of the menstrual cycle, the female’s body will prepare for ovulation, meaning that for those women whose cycles regularly last 28-30 days, the 14th-15th days subsequent to the start of the period is when ovulation will occur. At this time, the body will produce progesterone to thicken the endometrium for around 2 weeks in order to prepare it for fertilization. Then, if the female is not impregnated, the brain will send signals to halt progesterone production and the thickened endometrial walls will become displaced, exiting the body as menstrual bleeding.
Menstruation postponement medication contains the progesterone group of hormones, which work by stopping the thickened endometrium from being displaced. Those wishing to postpone their period must be certain of the dates involved in their menstrual cycle. For instance, in a case where the period arrives on the 29th day of each cycle and regularly lasts 2-3 days, it means that ovulation will occur around the 14th-15th of the cycle. Hence, if a woman wishes to postpone her period, progesterone levels must be maintained by lengthening the natural production of progesterone which begins around the middle of the cycle. This can be done by taking progesterone drugs according to the number of days by which they wish to postpone the period. Then, once taking the drugs is discontinued, the endometrium will immediately be displaced and the menstrual bleed will occur.
