What is the reason for irregular menstruation? I haven’t had my period for a month and a half.

1. Pregnancy: If a woman who has sex in the near future finds that she has not had her period for two months, she must verify whether she is pregnant. Because "menopause" is the first sign of pregnancy, if you have not had sex or are pregnant, please consider other factors.

2. Emotional abnormalities, such as long-term depression, mental stress, or major mental stimulation and psychological trauma, can lead to menstrual disorders or dysmenorrhea, amenorrhea. This is because menstruation is caused by hormones secreted by the ovaries on the endometrium. Ovarian hormone secretion is controlled by hormones released by the pituitary gland and hypothalamus. Whether the ovaries, pituitary gland or hypothalamus function abnormally, it will affect menstruation.

3. Women's menstrual period is stimulated by cold, which will cause excessive contraction of pelvic blood vessels and lead to delayed menstruation. Women should pay attention to the menstrual period and prevent colds and dampness.

4. Girls should have at least 17% body fat, which can occur before menarche, and at least 22% body fat in order to maintain a normal menstrual cycle. Overeating, due to insufficient energy intake, leads to a large amount of fat and protein consumption in the body, resulting in estrogen synthesis disorders, affecting menstruation, causing a small amount of menstruation or amenorrhea. Women who pursue slimness should not eat blindly.

5. Some ingredients and alcohol in cigarettes interfere with physiological processes related to menstruation, leading to menstrual disorders. Among women who smoke and drink excessively, 25% to 32% of women who smoke more than 1 pack a day or drink more than 100 ml of alcohol have menstrual disorders, which is three times higher than women who do not smoke or drink. Women should not smoke or drink less.
