Is it pregnancy if menstruation suddenly decreases?

Oligomenorrhea refers to a significant decrease in menstrual volume. Some female patients have a menstrual period of less than two days, with a menstrual blood volume of less than 10ml or so little that even a double layer of toilet paper cannot be wet, which is called oligomenorrhea. The total amount of menstrual discharge for an average person is between 50 and 60 ml. Next, let’s discuss whether it means you are pregnant if your menstrual period suddenly becomes less frequent.

Causes of scanty menstrual flow

1. Ovarian decline

As women age, their ovaries will gradually decline, which will also lead to a decrease in menstrual volume, which is a normal physiological phenomenon.

2. Uterine wall damage

Menstruation is actually a bleeding phenomenon caused by the shedding of the uterine wall. It will change with the changes in the ovarian cycle. If the uterus is hypoplastic, it will naturally lead to less shedding of the uterine wall, and the direct manifestation is less menstrual flow. In addition, damage to the uterine wall caused by abortion, curettage, etc. can also lead to scanty menstruation.

3. Endocrine disorders

Endocrine disorders can also cause women to have less menstrual flow, which is mainly caused by the imbalance of estrogen and androgen metabolism levels in the body. If the estrogen level is too low, it can cause uterine wall hypoplasia in women. The weak uterine wall is bound to be unable to meet the normal menstrual volume, which is clinically manifested as less menstrual volume. If people lose weight too much or have irregular eating and living habits, it will cause endocrine disorders.

4. Changes in the spiritual environment

Nowadays, women who have just entered the workplace are under great pressure. They are in a state of high mental anxiety for a long time, which will cause metabolic imbalance in women, which is clinically manifested as less menstrual flow.
