My period is not coming and I am not pregnant

The normal menstrual cycle of a normal person is about 28 to 30 days. It is normal to be seven days earlier or later. Because everyone's physique is different and affected by adverse environmental conditions, there may be some changes. However, women should pay attention during their period. If their period does not come for a long time and exceeds seven days, and they are not pregnant, it cannot be ruled out that it is caused by medication, surgery or other factors.

1. Pregnancy can be detected 7 days after the menstruation is delayed. The urine can be tested with the "Early Pregnancy Test Strip". If the result is positive, it is very likely that the pregnancy is present. If the "Early Pregnancy Test Strip" 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 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.
