My period hasn't come for 3 days.

The phenomenon of delayed menstruation has happened to almost every woman. For those women who do not want to get pregnant, they may feel panic when their menstruation is delayed. However, for women who are preparing for pregnancy, they will be particularly happy when their menstruation is delayed, thinking that they may be pregnant. In fact, if the menstruation is delayed within ten days, no treatment is needed. So what is going on if the menstruation is delayed for three days and has not come?

It is not a big deal if your period is delayed by less than ten days. However, if your period is delayed by more than ten days, it is best to go to the hospital for a detailed examination.

The menstrual cycle is generally 28 to 30 days. About ten days earlier or later is still within the normal range, and the length of the cycle varies from person to person. But if it exceeds this time, women with normal menstruation will definitely be worried. There are four situations:

1. Pregnancy

Ten days after the menstruation is delayed, you can test your urine with an early pregnancy test strip. If it is positive, you are very likely pregnant. If it is negative, the opposite is true. 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. The amplitude of the drug effect

If endocrine disorders occur after taking contraceptives, menstruation may be delayed. 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

For example, intrauterine surgery may cause cervical adhesions, which may lead to menstrual blood stasis and thus delay menstruation.

4. Others

Such as psychological factors such as mental tension, stress, environmental changes, and some diseases that affect endocrine system. Can cause delayed menstruation.

Expert tip: If menstruation is delayed only 1-2 times occasionally and there are no other accompanying symptoms, it does not fall into the category of menstrual disorders. When the interval between menstrual cycles is more than 35 days, it is called oligomenorrhea, and when menstruation stops for more than 3 menstrual cycles, it is called amenorrhea. The absence of ovulation after amenorrhea can also lead to problems such as osteoporosis and endometrial hyperplasia, which must be taken seriously. It is recommended to go to the hospital for examination and treatment.
