For women, because there are always special days of the month, when encountering special things inevitably annoy people! For example, exams, field training, travel or other special tasks that require avoiding menstruation days, hoping that it would be nice to have the period early or late if you want it to be. Medical advances can do this. However, considering that the normal physiological cycle of the human body is disturbed, in order to minimize its impact on the human body and not lead to menstrual disorders in the future, it is recommended to advance or delay 1 week at most, because the average normal menstrual cycle is 28 days, advance or delay 7 days is also in the normal range. Of course, a longer advance or delay is possible. It should be said that theoretically, it is possible to be “free” of menstruation. If you choose to take the oral contraceptive pill Mafulon, if you want to postpone your period to the 17th of next month, you can take Mafulon continuously from the first day of your period to the 17th of next month. 2. Starting from the 16th day of menstruation, take 8-10mg of progesterone daily orally until the day you want to avoid it. 3. Women should be reminded that although you gain freedom in your menstruation, there is a price to pay, which may lead to future disruptions in your menstrual cycle ranging from 1-3 months. Therefore, you should not use them for a long time, and even more so, you should not use them arbitrarily, and you should always seek medical advice first. In addition, some people who take these drugs orally may experience dizziness, nausea, vomiting and other reactions. Lastly, it should be noted that it should not be used by women older than 40 years old, breastfeeding, women with hypertension, diabetes, liver and kidney disease, thyroid disease, thromboembolic disease, or women with malignant tumors of the breast or reproductive organs or suspected tumors.
