Yosmin is a combination of estrogen and progesterone, a short-acting contraceptive that can also regulate menstruation. If used to regulate the menstrual cycle, simply taking it for one month or two months will not achieve the purpose of regulating the menstrual cycle, and it is necessary to continue to take the drug. For healthy women, Yosmin can be taken continuously, but one thing to be aware of is that Yosmin has a serious adverse effect, which is the possibility of thrombosis. The risk of thrombosis is higher in the first three months of taking the drug or in the first three months of restarting the drug after stopping it, and this risk decreases as the time of taking the drug increases. If you apply Yosmin to adjust your menstrual cycle, it is recommended that you take the drug for three consecutive months or up to half a year, and only in this way can you adjust your menstrual cycle.
