Occasionally, a month without menstruation may be normal, and there is no need to worry.
The arrival of menstruation can be affected by a variety of factors. When a woman is overworked, emotionally upset, has an eating disorder or changes her living environment recently, it may cause her body to experience a short-lived endocrine imbalance, resulting in her menstruation failing to arrive on schedule. After rest and recuperation, the body will gradually recover and menstruation will become normal again in the second month.
However, in the case of regular menstruation and suddenly no menstruation for a month, if the woman is sexually active, she should first go to the hospital for a blood HCG test to rule out the possibility of pregnancy.
Therefore, there is no need to worry about just an occasional month without menstruation, but if the lack of menstruation occurs frequently, you should go to the hospital for a sex hormone and ultrasound examination to clarify the cause.
