Why do girls not have their periods?

Women in daily life often have such an experience that their menstrual period does not "come according to the usual rules" in a certain month. Sometimes it comes a few days early, sometimes a few days later, and sometimes it doesn't come at all, which is really frustrating. The normal menstrual cycle of a normal girl is generally about 28 days. It is normal to be 7 days early or late. So what is the reason why girls do not have their periods for a long time?

Pregnancy: Women whose menstruation is delayed for 10 days and have not come yet and who have had sexual intercourse recently must pay attention, because it may be caused by pregnancy. At this time, you can go to the pharmacy to buy a pregnancy test strip for testing. If you are worried that the test result is inaccurate, you can go to the hospital for a B-ultrasound.

Emergency contraception: Emergency contraception is not unfamiliar to everyone. Nowadays, many women choose emergency contraception for contraception, which not only can achieve the actual effect of contraception but also is relatively affordable. However, the side effects of emergency contraception on the body are still relatively large, and it is very easy to cause delayed menstruation.

Endocrine imbalance: It is a more common cause of delayed menstruation. Factors such as psychological tension, anxiety, excessive work pressure, and long-term depression will cause endocrine imbalance in the human body, which will lead to delayed menstruation in women.

Intrauterine surgery: The reason why some women delay their menstruation may be that they have undergone some intrauterine surgery, which caused cervical adhesion. After the cervix of women has adhesion, it is very easy to cause menstrual blood stasis, which leads to delayed menstruation.

Tuberculous endometritis: Tuberculosis bacteria invade the uterine wall, causing inflammation of the uterine wall, which is damaged to varying degrees and forms scar tissue, leading to amenorrhea, so women are unable to menstruate again and again.
