Why am I not pregnant and not having my period?

The adjustment of the menstrual cycle is a relatively complex process, which mainly involves the hypothalamus-pituitary gland, pituitary gland and uterus and ovaries. The hypothalamus-pituitary gland secretes growth hormone, which controls the ovaries by regulating the secretion of pituitary gonadotropin. The estrogen secreted by the uterus and ovaries has a feedback effect on the hypothalamus-pituitary gland and pituitary gland. So what is the reason for not having menstruation even if you are not pregnant?

Delayed menstruation often occurs, which may be related to this reason. In severe cases, it may cause infertility.

Cold diet: When approaching the menstrual period, the diet should be light and nutritious, especially cold foods must not be eaten. If eaten, it will cause delayed menstruation (the same principle applies to catching a cold. If women do not pay attention to protect themselves, wear too little in winter, or come into contact with cold water, it will also affect the menstrual cycle).

Staying up late for a long time: If a woman stays up late for a long time, her endocrine system will be unbalanced, which will then affect her menstrual cycle and cause delayed menstruation.

Depression: Depression, irritability, stress, and anxiety can all affect the normal endocrine function, thus causing delayed menstruation.

Fasting to lose weight: Some women fast to lose weight, and the intake of calories, fat, and protein are very small. In the long run, it will inevitably cause endocrine imbalance, which may lead to delayed menstruation at the mildest and amenorrhea at the worst.

Taking hormones: Some women often take hormones, which can also cause delayed menstruation.

Chronic diseases: There may also be physiological reasons that cause menstrual disorders and subsequent delayed menstruation.

Menstruation is the regular shedding and bleeding of the uterine wall that occurs with the regular changes of the uterus and ovaries. The occurrence of regular menstruation is an important indicator of complete reproductive function. Normal menstruation is regular and self-limited. The first day of bleeding is the beginning of the menstrual cycle. The time interval between the first days of two menstruations is called a menstrual cycle, which is generally 21 to 35 days, with an average of 28 days. The duration of each menstrual period is called the physiological period, which is generally 2 to 8 days, with an average of 4 to 6 days.

As we all know, the menstrual period will stop after pregnancy, and then until about 5-7 days after the menstrual period ends, you can use a pregnancy test stick to test. If it shows "two bars", you are pregnant. However, the relationship between pregnancy and the cessation of menstruation is not mutual. In other words, the menstruation will definitely stop during pregnancy, but the cessation of menstruation does not necessarily mean pregnancy.
