Is the ovulation period fixed?

For fertile female friends, menstruation and ovulation are two very important stages. We need to take special care of female friends during these two special periods. The ovulation period is not fixed. It is calculated based on the menstrual period of each female friend. The period may change every month, and the menstrual period will also affect mood and diet and other issues, and the ovulation period will change accordingly.

Is ovulation fixed?

A woman's ovulation date is generally about 14 days before the next menstrual period. Starting from the first day of the next menstrual period, counting down 14 days or subtracting 14 days is the ovulation day. The ovulation day and the 5 days before and 4 days after the ovulation day are called the ovulation period.

For example, a woman's menstrual cycle is 28 days, and the first day of this menstruation is December 2nd. Then the next menstruation will be on December 30th (December 2nd plus 28 days). Subtract 14 days from December 30th, and December 16th is the ovulation day. The ovulation day and the 5 days before and 4 days after it, that is, December 11-20, is the ovulation period. Except for the menstrual period and ovulation period, the rest of the time is the safe period.

Generally speaking, the time interval between ovulation and the first day of the next menstrual period is relatively fixed, which is 14 days.

The chances of a woman getting pregnant if she has sex during her ovulation period are relatively high. So, how many days does a woman's ovulation period last? In fact, many women who are planning to get pregnant are still not quite sure when their ovulation period is, nor do they know how many days it lasts. There are two types of ovulation periods in women:

1. Generally speaking, a woman's ovulation period is 10 days.

A woman ovulates once every menstrual cycle (usually once a month), and the day of ovulation is the ovulation day. Counting the days, about 14 days before the next menstrual period is your lucky day for pregnancy - ovulation day. The 5 days before and 4 days after ovulation day, together with the ovulation day, a total of 10 days are your ovulation period. If you have sex during the ovulation period, it is easy to "get pregnant", so couples who are preparing for pregnancy should seize the opportunity!

2. Not everyone’s ovulation period is 10 days.

As the pace of modern life continues to accelerate, women are increasingly affected by the real environment. In addition, women's emotions, diet, lifestyle habits, etc. all affect their ovulation. When a woman with a relatively regular life rhythm suddenly changes her life rhythm, her menstrual period may be advanced or delayed, and the length of the ovulation period will fluctuate with the change in the menstrual period. Therefore, the ovulation period of 10 days is an approximate statement, but in fact, the ovulation period of women is generally less than 10 days.

Reminder: The effective conception time during the ovulation period is generally 5 days before female ovulation, because sperm can survive in the female body for up to 5 days, and 2 days after female ovulation, because the egg can only survive in the female body for 2 days after being released. In other words, the effective conception time is generally about 7 days.

What are the symptoms of ovulation?

1. Changes in basal body temperature: During a menstrual cycle, the basal body temperature of normal women of childbearing age is lower before ovulation and rises after ovulation. Generally, the temperature difference between the two can reach about 0.5℃, showing a typical biphasic body temperature curve. This body temperature curve indicates that the ovaries have ovulation function, and the junction of the high and low body temperature curves is the ovulation date of the ovaries.

2. Cervix and cervical mucus: During the ovulation cycle, the cervix is ​​affected by estrogen and progesterone, causing changes in secretion and opening and closing. As the follicles develop, the secretion of estrogen increases, the cervix relaxes and opens, the amount of mucus increases, the viscosity is minimal, it is clear and transparent like egg white, and the tension (stringiness) gradually increases; after ovulation, under the influence of progesterone, the amount of mucus secretion rapidly decreases and thickens, and the cervix closes.

3. Ovulation pain: This is a symptom of ovulation. About 1/3 of women experience ovulation pain. The pain occurs in the lower abdomen on the side of ovulation. It is severe pain or continuous dull pain and lasts for 6-12 hours. During ovulation, due to the increase of prostaglandins in the body, the pressure in the follicular fluid cavity increases, and the surface of the ovary will rupture to release the egg. This rupture process can cause lower abdominal pain in some sensitive women.

4. Ovulation bleeding: It is a symptom after ovulation, usually lasting for 2-3 days. The amount of bleeding is not much, and sometimes it only manifests as slightly red leucorrhea. Ovulation bleeding may be caused by the fact that after the mature follicle ruptures and ovulates, the estrogen level drops sharply, unable to maintain normal endometrial growth, causing local shedding of the surface layer of the endometrium, resulting in breakthrough bleeding. Bleeding may be accompanied by pain and discomfort in the lower abdomen, which generally does not require treatment.

5. There is also a decrease in appetite, increased libido and decreased resistance.
