There is nothing wrong with not getting progesterone for your period. In general progesterone injection, which is a purely natural preparation, can be used for the treatment of irregular menstruation and birth control. If the period does not come, ruled out because of pregnancy, you can give intramuscular injection progesterone 20mg, once a day for 5 days, withdrawal bleeding will occur 3-7 days after stopping the drug. However, the absence of menstruation should be considered according to the situation, and the necessary tests, such as ultrasound, hormone six tests, etc., should be given to regulate the symptoms, and progesterone should not be used as a means to regulate menstruation. If you take progesterone every time you don’t have a period, it will cause the endometrial lining to become thinner, which will affect future conception and cause the ovarian function to decline. Therefore, it is important to check and give the right treatment afterwards.
