How many days does ovulation bleeding usually last?

Ovulation bleeding is a process that every female friend must go through. It happens once a month. During these few days, the endometrium is shed and ovulation begins to occur. At this time, you cannot have sex because it will damage your uterus. Next, let’s find out how many days ovulation bleeding usually lasts.

The so-called "ovulation bleeding" refers to a small amount of vaginal bleeding caused by ovulation in the middle of two menstrual periods.

Normal menstruation for women occurs every 28 to 30 days (may also fluctuate by 3 to 5 days), and the menstrual period lasts for 3 to 5 days (may also fluctuate by 2 days). Regular ovarian ovulation is the fundamental guarantee for normal menstruation. Women have two ovaries, one on each side, located behind and below the fallopian tubes on both sides of the uterus. They produce eggs and sex hormones to maintain women's normal menstrual physiology and reproductive function. In a mature female, generally one follicle matures and releases a mature egg every month. Ovulation usually occurs in the middle of two menstrual periods, roughly about 14 days before the onset of menstruation.

A woman's menstrual cycle can be simply divided into 4 periods:

1. Menstrual period, which is the period from the onset of menstruation to the end of menstruation;

2. Preovulatory period, which is the period from the onset of menstruation to ovulation;

3. Ovulation period, which is the period of time when the egg is released;

4. Late ovulation is the period from the time the egg is released to the time before the next menstrual period.

During the preovulation period, the follicles gradually develop to maturity and secrete estrogen and a small amount of progesterone. Estrogen gradually repairs the endometrium during the bleeding period and stops the bleeding. As the secretion of estrogen increases, the repaired endometrium gradually thickens (called a proliferative reaction). Before ovulation, estrogen levels reach a peak. During ovulation, the mature follicle ruptures and the egg is released. The estrogen level drops rapidly, causing the endometrium, which has been proliferating due to the nourishment of estrogen, to lose support and cause a small amount of bleeding. Under normal circumstances, this bleeding is extremely short (about 1 to 2 hours), and only red blood cells can be seen in the leucorrhea under a microscope. After ovulation, the ruptured follicle quickly collapses and closes to form a corpus luteum, which secretes progesterone and a small amount of estrogen, causing the endometrium, which is in a proliferative reaction, to continue thickening (called a secretory reaction).

In the article, we learned how many days ovulation bleeding usually lasts. First of all, it depends on your personal physical condition. For some people, it lasts 3-5 days, and for others, it lasts 7 days. Generally speaking, under normal circumstances, these are all normal.
