The vast majority of women, if there are no other problems, will have their period once a month, usually in a cycle of 28-30 days. If menstruation is not regular or is often delayed, it is advisable to have the appropriate investigations and laboratory tests to understand the endocrine situation before treatment. For example, a blood test for sex hormone 6 can be done on the second or third day of menstruation to find out the endocrine status, and a blood test for thyroid function is also recommended to find out whether irregular menstruation is caused by thyroid abnormality, and then treatment can be given based on the results of the test. After treatment, most menstruation will return to normal. For example, if the menstrual irregularity is caused by endocrine disorders, or if there is a menstrual disorder, you can do artificial cycle treatment. Start taking Tonicare orally on the 5th day of menstruation, take 1 tablet once a day for 21 days. When the 16th tablet is taken, add progesterone, take 2 capsules once a day for 5 days and stop taking it together with Jiajiale, and your menstruation will come in 3-7 days after stopping the medication.
