Reasons for a week late menstruation

Menstruation is a physiological phenomenon unique to women. It is a behavior that women perform to protect and renew their reproductive system in order to reproduce offspring. Therefore, women pay more attention to menstruation. Moreover, every cyclical arrival of menstruation will cause women to have some physical reactions, which provides some basis for women to predict menstruation. However, some women’s menstruation is delayed by a week, and they don’t know what’s going on. Let’s take a look at the introduction of menstruation being delayed by a week.

The menstrual cycle is generally 28 to 30 days. About 7 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. Pregnant

You can use the "Early Pregnancy Test Strip" to test your urine 7 days after your period is delayed. If the result is positive, you are very likely pregnant. If the result 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. The amplitude of drug effect

For example, 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 gastrokinetic 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. Surgery caused

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

From the above introduction, it can be seen that the reality that menstruation is one week late is a relatively normal phenomenon for women. The occurrence of this phenomenon indicates that women may have symptoms of physical fatigue. At this time, women should stop and rest, or go to the hospital to check their bodies to see if there is anything wrong.
