My menstrual period was very regular but suddenly got delayed.

If a woman's menstrual cycle has always been regular but is suddenly delayed, it may be that she is pregnant. You can choose to check with an early pregnancy test. It may also be because the woman has been in a bad mood and has irregular work and rest recently, causing menstrual irregularities. Unclean sexual life can also cause menstrual disorders. So for the sudden delay of menstruation, everyone can understand its reasons.

1. Pregnancy can be detected 7 days after the menstruation is delayed. You can use the "Early Pregnancy Test Strip" to test urine. If the result is positive, you are very likely to be pregnant. If the "Early Pregnancy Test Strip" is negative, then vice versa. But if you are pregnant, there will be other symptoms such as nausea, breast tenderness, etc. Of course, the last resort is to go to the hospital for an ultrasound examination.

2. Side effects of drugs, such as endocrine disorders after long-term use of contraceptives, can also cause delayed menstruation. Doctors also found, based on patient feedback, that a new generation of gastric motility drug, metoclopramide, also known as domperidone, may also cause this condition. Since metoclopramide does not easily cross the blood-brain barrier, it is believed that it has no inhibitory effect on central dopamine receptors. Central dopamine receptors are inhibited, resulting in a decrease in the amount of hypothalamic release factors entering the anterior pituitary. As a result, the anterior pituitary secretes less gonadotropin and corticotropin, leading to amenorrhea and delayed ovulation.

3. Caused by surgery, such as uterine surgery causing cervical adhesions and resulting in menstrual blood stasis, thus delaying menstruation.

4. Nutritional status.

5. Mental factors: Abnormal fluctuations in emotions such as excessive tension, sadness, joy, etc. will inevitably interfere with the normal work of the central nervous system, thereby affecting the regulation of ovarian function that determines menstrual changes and causing menstrual disorders.

6. Changes in external working conditions, living environment, climate, etc.: Irregular daily living habits, getting up early and going to bed late without good rest, or sudden cold or overheating of the climate can cause menstrual disorders in women. In your case, it is recommended that you go to the hospital for relevant examination as soon as possible. Active treatment should be given after the cause is identified.

7. Long-term exposure to harmful radiation, chemotherapy drugs, etc. may also cause premature ovarian failure and delayed menstruation. Pay attention to ovarian protection. For older women (over 40 years old), delayed menstruation and exclusion of other endometrial lesions are mostly caused by the gradual decline in ovarian function, and no special treatment is required clinically.

If your menstruation has been very regular but is suddenly delayed, female friends should not worry first. If you have had sexual intercourse, you can go to a regular hospital for an ultrasound examination or a blood test for HCG to rule out the possibility of pregnancy. Secondly, if you are not pregnant, then consider that the delayed menstruation is caused by endocrine reasons. Then find out the cause and adjust it in a targeted manner.
