My period came on November 5th but didn't come on December 5th

If your period that started on November 5th has not come by December 5th, it could be normal physiological fluctuations, or there could be other reasons. Let's look at the possibilities behind this.

1. Normal physiological phenomenon: The menstrual cycle is not always exactly 28 days. Many women's cycles fluctuate slightly, and it is common to be one week early or late. If it is just an occasional delay, you may not need to worry too much. Observe for a while to see if it returns to normal.

2. Possibility of pregnancy: If you have a history of sexual activity, especially if you do not take contraceptive measures, delayed menstruation may be a sign of pregnancy. At this time, the most direct way is to go to the hospital for a human chorionic gonadotropin (HCG) test. This test can help confirm whether you are pregnant.

3. Endocrine disorders: Our lifestyle directly affects the endocrine system. Excessive stress, frequent late nights, and irregular diet may disrupt the endocrine system, thereby affecting the menstrual cycle. It is recommended to try to adjust your lifestyle, such as regular work and rest, healthy diet, and moderate exercise, which will help restore a normal menstrual cycle.

4. Premature ovarian failure: Premature ovarian failure can cause changes in hormone levels in the body, which in turn affects menstruation. If you suspect this is the cause, you can go to the hospital for six sex hormone and ovarian function tests. Based on the test results, the doctor may recommend the use of medication for conditioning.

5. Other factors: In addition to the above reasons, drastic changes in weight, excessive exercise, and eating disorders may also affect menstruation. Maintaining a healthy weight and eating habits are important factors in maintaining a normal menstrual cycle.

In the case of delayed menstruation, it is important not to be too nervous. Proper self-observation and lifestyle adjustments are helpful. If the situation persists or is accompanied by other discomfort, it is recommended to seek medical attention in time. Through professional medical examinations, you can find the problem more clearly and get appropriate treatment and advice. I hope this information can bring you help and peace of mind.
