Will having sex on the day of ovulation definitely lead to pregnancy? Is the pregnancy rate on the day of ovulation definitely high?

Many people should have discovered that some people pay close attention to their ovulation day during pregnancy preparation. The chances of pregnancy for couples having sex on the ovulation day will be greatly increased. Many people are not quite sure whether the pregnancy rate is really high if they have sex on the ovulation day.

The answer is not necessarily. Ovulation day refers to the time when women are most likely to get pregnant, but it does not mean that having sex on ovulation day will definitely lead to pregnancy. If you want to get pregnant, don't focus on ovulation day.

The possibility of conception outside of the ovulation period is also very high. In many cases, because a woman's ovulation period can change due to many factors such as emotions and environment, early ovulation and accidental ovulation may occur, so there is a chance of pregnancy even if you have sex outside of the ovulation period. Similarly, for couples who have not yet planned to have a baby, if they completely treat the time outside of the ovulation period as the so-called safe period and do not take any contraceptive measures during sex, the chance of accidental pregnancy is very high.

A healthy woman normally releases a mature egg every month. After the couple has sex, if the mature egg can meet the sperm and combine successfully, the egg becomes a fertilized egg, indicating that conception is successful. Couples who are planning to get pregnant should make good preparations before pregnancy, such as doing pre-pregnancy checkups, exercising regularly, eating a balanced diet, quitting smoking and drinking, and adjusting their work and rest schedules.

It is said that women have a higher chance of getting pregnant on the day of ovulation than on other days, but in fact, we should not be too superstitious about the day of ovulation, because some women are more likely to get pregnant the day before ovulation. Why? This is related to the survival time of sperm and egg, and the path of sperm.

It takes a certain amount of time for sperm to reach the fallopian tube from the vagina after being ejaculated from the male body. Sperm of good quality can swim about 4 mm in one minute, and it takes about 45 minutes to complete the journey. If it is a weaker sperm, it may take 3 days to complete this journey. Under normal circumstances, sperm can survive for 48-72 hours during this process, but unfortunately the egg can only wait for 12-24 hours. If the couple only has sex on the day of ovulation, and the sperm swims slower, the egg is likely to wither before it can wait. Therefore, having sex the day before ovulation and letting the sperm start on the road first may increase the pregnancy rate. Of course, what we said above is only for general situations, and does not rule out other possibilities. The actual situation of sperm and egg should also be considered.

The ovulation date of a woman can be roughly calculated based on her menstrual cycle, but sometimes the result may not be accurate. If you want to get more accurate data, you can also use the following method to test it. The following method is especially suitable for women with irregular menstrual cycles.

1. Basic body temperature detection method

Every morning after waking up and before getting up to move around, measure your body temperature for 3 minutes and record the measurement data in a timely manner.

Women's basal body temperature is as regular as their menstrual cycle. Women's body temperature usually rises by 0.3℃-0.5℃ from the day of ovulation to the next menstrual period. The basal body temperature of a normal ovulating woman lasts for about two weeks from the first day of menstruation to the day of ovulation, and the high temperature period also lasts for two weeks. This phenomenon of low temperature at the beginning and high temperature at the end indicates that the ovulation function of the ovaries is normal, and ovulation usually occurs before or during the rise of body temperature.

2. Changes in vaginal discharge

Vaginal secretions in women generally come from cervical mucus. The secretion will gradually increase before ovulation and become thinner and translucent. During ovulation, the amount of mucus is the largest and is stringy, looking like smooth egg white. The phenomenon of large amounts of mucus secretion during ovulation will last for 2-3 days. After ovulation, the changes in progesterone prevent the secretion of mucus, and the vaginal secretion begins to decrease. One thing that should be noted is that the appearance of vaginal secretions in women under pathological conditions will be different from the above-mentioned egg white, and then you should see a doctor.

3. Test with ovulation test strips

The luteinizing hormone contained in female urine usually reaches a peak within 2 days before ovulation. The peak level of luteinizing hormone can be measured more accurately using ovulation test strips. The ovulation day detection with test strips should be carried out at a fixed time every day. If the luteinizing hormone is approaching its peak, the color of the test line of the test strip will gradually deepen. At this time, it should be tested every 12 hours until the peak appears. The method of using ovulation test strips to test the ovulation day has a high accuracy rate and is an ideal method.

Women should start testing on the tenth day after their period, initially once a day until the color of the test line gradually becomes darker, then increase to once every 4 hours, and try to get a strong positive result because ovulation occurs when a strong positive turns weak.

In order to get pregnant faster, many couples who are planning to have a baby pay close attention to the ovulation day of women. So, how to calculate the ovulation day?

1. Women with regular menstrual periods

For women with regular menstrual periods, the ovulation day is generally the 14th day before the next menstrual period. The 5 days before the 14th day and the 4 days after the 14th day (including the 14th day) are called the ovulation period. This shows that a woman's ovulation period is generally ten days.

For example: a woman has a regular menstrual cycle, which is usually 30 days. This time, she has her menstrual period on July 25th, and the next menstrual period will be on August 25th. The ovulation day is 14 days before August 25th, that is, August 11th. The 5 days before the ovulation day is August 6th, and the 4 days after the ovulation day is August 15th, so the ovulation period is from August 6th to August 15th. In other words, subtract the date of the end of this menstrual period from August 6th. For example, if this menstrual period comes on July 25th and ends on July 30th, then the ovulation period is 6 days after the menstrual period.

2. Women with unstable menstrual cycles

For women with irregular menstrual cycles, the method to calculate the ovulation period is: subtract 18 days from the shortest menstrual cycle, which is the first day of ovulation.
