Is it pregnancy if the menstrual period comes?

Menstruation is an important metabolic activity of the female reproductive system, and women will not have menstruation during pregnancy. Therefore, no matter how much or how little menstruation comes, as long as it comes, it means that the woman is not pregnant. Of course, scanty menstruation is also a phenomenon that women should pay close attention to, because it may mean that there are certain health problems in their bodies. Below, we will introduce the relevant knowledge in detail.

1. Is it pregnancy if menstruation comes a little?

Every woman will have her period when she reaches puberty. This is a normal physiological phenomenon. Menstruation is not only a proof of whether a woman is fully developed, but also reflects her physical condition. For example, if a woman's menstrual flow suddenly decreases, it is very likely caused by an illness. If a woman suddenly stops having her period, it may also be due to certain diseases. Of course, the sudden absence of menstruation may also be caused by pregnancy. However, if a woman has her period but the amount of menstrual flow becomes less, it means that there is a problem with the woman's physical health and it has nothing to do with pregnancy.

In fact, pregnancy will only cause a woman's menstruation to disappear, but will not reduce the amount of menstruation. Therefore, if a woman's menstrual volume suddenly decreases, it is very likely that she has a certain disease, and it is definitely not caused by pregnancy. Therefore, when a woman finds that her menstruation is abnormal, she must go to the local hospital for treatment in time to avoid delaying the disease and causing harm to the woman's health. In addition, abnormal menstruation can easily cause infertility, so everyone must pay attention to it.

2. Reasons for scanty or absent menstruation

There are many reasons why women do not have menstruation. It is very likely caused by certain gynecological diseases. In addition, endocrine disorders can also cause women's menstrual volume to suddenly increase or decrease. Therefore, a sudden decrease in women's menstrual volume has nothing to do with pregnancy. It is mainly caused by physical health problems. In addition, if women do not pay attention to their daily diet in daily life, eat some raw and cold foods, or eat hemostatic foods such as mangoes during menstruation, they will also experience symptoms of decreased menstrual volume.

3. Basic introduction to menstruation

The uterus bleeds once a month, which is called menstruation. The ovaries have the functions of laying eggs, releasing ovulation and producing hormones. The hormones secreted by the ovaries are mainly estrogen, progesterone and androgen. Among them, estrogen is very important for maintaining the cyclical development and function of sexual organs, secondary sexual characteristics and ovaries. Progesterone mainly acts on the uterus to ensure the progress of pregnancy. Androgens increase sexual desire and are also involved in the regulation of follicle growth and egg maturation.

When a woman reaches puberty, the follicles mature and, with the help of luteinizing hormone, the follicles secrete estrogen and stimulate the endometrium to undergo proliferative changes. The amount of estrogen gradually increases, causing the endometrium to thicken, the glands to increase in number and lengthen, becoming curved, and the blood vessels to become spiral, which is called the proliferative endometrium. This is approximately day 11 to 14 of the full-term menstrual cycle. At this time, estrogen reaches its peak, and a large amount of estrogen acts on the hypothalamus, causing the pituitary gland to release a large amount of luteinizing hormone, thereby promoting ovulation of mature follicles. After ovulation, the ruptured ovum forms a corpus luteum. The corpus luteum secretes progesterone, which, together with estrogen, causes the endometrium to enter the secretory phase. If fertilization is not achieved at this time, the corpus luteum will atrophy, the secretion of progesterone and estrogen will decrease, the endometrium will not receive support from sex hormones, and will undergo necrosis and shedding, leading to menstruation. This is why the uterus produces menstruation.
