Is it normal to bleed three days before your period?

Menstruation is a physiological phenomenon that women attach great importance to, because abnormal menstruation will bring great harm to health and seriously disrupt women's lives. Menstrual problems are indeed quite common in life, and they bring pain to many women. For example, women need to pay attention to bleeding in the few days before menstruation. Let’s take a look at whether bleeding in the first three days of menstruation is normal?

If you often have a small amount of vaginal spotting before normal menstruation, it may be related to luteal insufficiency. You need to take an appropriate amount of progesterone under the guidance of a doctor about 14 days before the next menstruation. It has a certain conditioning effect. It is recommended to keep the vulva clean and hygienic at ordinary times.

The normal menstrual period is 3-7 days, with an average of about five days. There will be a small amount of brown vaginal discharge when the menstruation just starts and when the menstruation is about to end. This is also normal. If you have a small amount of vaginal bleeding every time you are about to have your period, this is normal, so there is no need to worry too much as long as the menstrual volume and menstrual period are within the normal range.

A small amount of bleeding before normal menstruation that continues until the onset of menstruation is a type of bleeding caused by luteal insufficiency, also known as luteal phase defect. It refers to the incomplete function of the corpus luteum formed by the follicle after ovulation, insufficient secretion of progesterone, or premature degeneration of the corpus luteum, resulting in a decrease in the secretory responsiveness of the endometrium. Clinically, the main features are delayed development of the endometrium during the secretory phase and asynchrony between endometrial development and fertilized egg development. It is closely related to infertility or miscarriage, and is generally manifested as shortened menstrual cycles and frequent menstruation. It is recommended to measure the progesterone P level in the mid-luteal phase on days 22-24 of the menstrual cycle.

If a woman experiences vaginal bleeding symptoms that do not occur during her menstrual period, it is possible that the secretory function of the ovaries is disturbed, causing uterine bleeding. In addition, if the follicles rupture during the menstrual period, causing a temporary drop in estrogen levels, this can also cause uterine bleeding symptoms. Of course, it may also be caused by genital tumors, such as cervical cancer, uterine fibroids, or endometrial cancer, which cause vaginal bleeding.
