Whether or not you will have your period on time in the second month after taking progesterone to induce menstruation depends on whether or not your body’s hormone levels are normal in terms of secretion and endometrial proliferation and transformation. The endometrium of a woman is regulated by the hormones secreted by the ovaries, and there is cyclical proliferation, transformation and shedding to form menstruation. Therefore, the normalization of menstruation depends on the level of hormones secreted by the ovaries and the normalization of endometrial proliferation and transformation. Taking progesterone to regulate menstruation is usually seen in the case of luteal insufficiency, with less progesterone secretion, resulting in the endometrium not being able to transform from the proliferative phase to the secretory phase, and thus not being able to shed to form menstruation. The second month after the use of progesterone to promote menstruation, if a woman’s body estrogen and progesterone secretion level is normal, the endometrium proliferation, transformation is normal, usually will come to menstruation. If the female body estrogen and progesterone secretion is not normal, the endometrium can not be normal proliferation, transformation, to a large extent, can not come to menstruation on time. If a woman has irregular menstruation, she must consult a doctor in time to avoid delaying her condition.
