The main clinical method to delay menstruation is to take progesterone capsules orally. Progesterone capsules belong to a hormone class of drugs whose main ingredient is progesterone. Progesterone can maintain the endometrium in the uterus in the secretory phase, which pushes back the shedding of the endometrium and thus has the effect of delaying menstruation. For women who want to postpone their menstruation, progesterone capsules are mostly taken orally a few days before the onset of menstruation and continue until the time needed. After stopping the oral progesterone capsules, women’s menstruation will come naturally, but it is not recommended to take progesterone orally for a longer period of time, otherwise it will cause endocrine disorders in women. If you need to postpone the onset of menstruation urgently, it is not recommended to take progesterone capsules orally, as this time is often a failure to postpone menstruation. Therefore, in order to ensure the effect, it is recommended that women take progesterone capsules orally early to postpone their menstruation.
