The best way to prolong menstruation is usually to take a short-acting oral contraceptive pill, which is started on the 5th day of menstruation, for example, you can take Eusebio, which is taken once a day without missing a dose. A woman will not get her period while taking the pill, and it will lead to the onset of menstruation 3-5 days after stopping the pill. Eusyn will slow down the growth of the endometrium, which contains a certain amount of estrogen and progesterone, and the lower amount will slow down the growth of the endometrium, thus delaying menstruation. In addition, women can also take progesterone soft capsules and other progestin drugs, which are taken in the second half of the menstrual cycle, i.e. after ovulation, during which menstruation does not occur, and the onset of menstruation will occur about 7 days after stopping the drug. However, if progestin drugs are taken frequently, certain side effects may occur, leading to menstrual disorders.
