What causes premenstrual bleeding?

Menstruation is the normal physiological cycle of the female body. However, abnormal problems may occur during menstruation. For example, some women may have their periods early or late. Whether it is early or delayed, the cause needs to be found and treatment needs to be given. Otherwise it will definitely affect pregnancy in the future. There shouldn't be too many symptoms before menstruation, but if a disease problem occurs, things before menstruation will not be normal. What causes premenstrual bleeding?

What if I have a small amount of bleeding a week before my period?

1. Vaginal bleeding one week before menstruation may be caused by luteal hypoplasia in the female ovaries after ovulation, or premature atrophy of the corpus luteum, which leads to insufficient secretion of estrogen and progesterone in the female body. The endometrium cannot be well maintained due to lack of hormones, resulting in small pieces of endometrium shedding.

2. If a woman has cervical polyps, cervical ectropion, or cervical erosion, she may experience irregular vaginal bleeding due to these conditions. Therefore, vaginal bleeding one week before menstruation is not a strange thing.

3. If a woman has just had a contraceptive device such as an IUD inserted, she may experience irregular vaginal bleeding after her first sexual intercourse. If the sexual intercourse occurs one week before her period, then this explains why vaginal bleeding occurs one week before her period. Female friends do not need to be too nervous about this and can just do the relevant hygiene care in a timely manner.

What is the reason for less menstrual flow?

1. There are three main reasons for dysmenorrhea and scanty menstruation: the first is abnormal uterine development. Menstruation will change with the female ovarian cycle, and the endometrium will peel off or bleed. If the uterus is abnormally developed, too small or deformed, only a small amount of endometrium will fall off during the menstrual period, and the menstrual flow will be less. Moreover, endometrial lesions or curettage can damage a woman's endometrium, causing her to have scanty menstruation or even amenorrhea.

2. Abnormal hormone secretion. Estrogen can stimulate the proliferation of the endometrium. Hormone abnormalities in the body can lead to insufficient thickness of the endometrium and less menstrual volume. Problems such as excessive dieting and bad mood in women will affect their endocrine environment, and abnormal hormone secretion will cause scanty menstruation. Anovulatory menstruation. Women who do not ovulate can also have menstruation. Unlike normal menstruation, the characteristics of this menstruation are irregular timing and less blood volume.

Through the above, I believe that all women have already understood the two questions of what causes a small amount of bleeding a week before menstruation and what causes a small amount of menstrual flow. Women with normal bodies must have normal menstruation, so in daily life, you should also pay attention to maintaining stable menstruation. Once there is an abnormality, do not take it lightly and actively go to the hospital to consult a doctor.
