Understanding women's ovulation period

For a normal female menstrual period, an egg will mature and be released after each menstrual period. This is the female's ovulation period. It is easy to get fertilized if you have sex during the ovulation period. Women have different ways of calculating ovulation. Everyone's physiological characteristics are different, so we need to understand our own bodies. There are several general calculation methods.

Basic Introduction

The ovaries of normal women of childbearing age release a mature egg every month. After the egg is released, it enters the fallopian tube and can generally survive for 1-2 days. The sperm produced by men is continuous. Sperm usually remains active in the female reproductive tract for 2-3 days, and its ability to conceive is within 48 hours. If a woman has sexual intercourse within a certain period of time before or after ovulation, she may become pregnant. This period of time is called the "ovulation period".

It is very important to grasp this period. On the one hand, it can give couples who are infertile due to missing the woman's ovulation period a great chance of conception; it can also enable couples who do not want to get pregnant temporarily to prevent conception by missing the "ovulation period" to have sex without other contraceptive measures.

2 Calculation method

Commonly used methods for calculating "ovulation period" are:

1. Cervical mucus observation method (must be done in the hospital).

2. Basal body temperature measurement method. That is: the basal body temperature is the temperature measured when the body wakes up after a long period of sleep (usually in the early morning) and before any activity or speaking. Under normal circumstances, the basal body temperature of women of childbearing age is lower in the first half of menstruation and even lower during ovulation. It may suddenly or slowly rise by 0.3-0.6℃ within 24 hours to a few days after ovulation.

Therefore, it is best to measure basal body temperature from the first day of menstruation, measure it every day, and record it on coordinate paper for observation and analysis.

3. Method for calculating menstrual date. That is: It is believed that each ovulation should occur about 14 days before menstruation, so the 5 days before ovulation to 5 days after ovulation is called the "ovulation period". However, this method is less reliable because most women have irregular periods. In comparison, the first two methods are more reliable, but somewhat troublesome. Here we introduce you to a simple and more reliable calculation method, hoping it will be helpful to you.

The calculation formula is:

First day of ovulation = the number of days in the shortest menstrual cycle minus 18 days

The last day of ovulation = the longest menstrual cycle minus 11 days

Before using this formula for calculation, the individual is required to observe and record his or her menstrual cycle for 8 consecutive times to obtain the longest and shortest number of days in his or her menstrual cycle. The numbers obtained by substituting them into the above formula represent the beginning and end time of the woman's "ovulation period" respectively. (The menstrual cycle is calculated from the first day of the current menstrual period to the first day of the next menstrual period) For example, the longest menstrual cycle of a woman of childbearing age in the first 8 months is 30 days and the shortest is 28 days. Substituting the formula into the formula is:

The first day of ovulation = 28 days - 18 days = 10 days The last day of ovulation = 30 days - 11 days = 19 days That is: this woman’s "ovulation period" starts on the 10th day of this menstruation and ends on the 19th day of this menstruation.

If our female friends have the above calculation method, it will be much easier to estimate the time of ovulation. However, the time of ovulation is not fixed, and sometimes even two mature eggs can be released. Female friends must pay attention to their health during menstruation, especially their diet, and avoid irritating foods that may cause symptoms of menstrual disorders.
