In order to delay menstruation, you can apply dexmedroxyprogesterone tablets, in which case it is necessary to calculate the date of the next menstrual period, in which the date is pushed back by 5-10 days, and on the pushed back date you can start the application of dexmedroxyprogesterone, the total length of the application date can be applied up to the pre-dated date of the intended period, and the period will come after the drug is discontinued for 1-2 days, and this is the general situation. During the application of dydrogesterone, the female organism itself has its own level of progesterone, as well as estrogen. Sometimes exogenous progesterone does not completely change the body’s own changes, so sometimes there is still irregular vaginal bleeding, so it is necessary to apply it with some foreknowledge.
