Can I get pregnant on the first day after my period?

In order to prevent pregnancy reasonably, you need to understand the operation of the menstrual cycle. It does not mean that a 28-day menstrual cycle is reasonable. The number of days in each person's menstrual cycle is different due to differences in weather, age, personal physical fitness and other reasons. Only by understanding your menstrual cycle can you calculate the correct ovulation day. This can help prevent pregnancy from a certain scientific perspective. So if you have sex on the first day after your period ends, will it lead to pregnancy?

Generally speaking, you will not get pregnant if you have sex during the safe period. The first day after the menstrual period is considered a safe period, but there are exceptions.

Ovarian ovulation usually occurs within two days before or after the 14th day of menstruation, so the safe period is approximately within 10 days after menstruation and within the 20th day after menstruation, until the next menstruation. The closer to the menstrual period, the greater the possibility of contraception, but this calculation method is often unreliable. Because the time of female ovulation is affected by factors such as the external environment, climate, her own emotions and health status, ovulation may be delayed or advanced, and extra ovulation may also occur.

In addition, the longest survival time of sperm and eggs in the female reproductive tract is uncertain, so the safe period cannot be calculated accurately. Therefore, under normal circumstances, the chance of a woman getting pregnant by having sex on the first day of menstruation is very small, but unexpected situations cannot be ruled out.

Women may have extra ovulation at any time, which is unpredictable. Although the probability of this happening is very low, it does exist. For safety reasons, I personally think that contraceptive measures should be taken during all sexual intercourse. Strictly speaking, there is no absolute safe period for women. Therefore, safe period contraception is not absolutely safe. Some couples who use the safe period contraception method, even if they strictly follow the requirements and regulations and avoid sexual intercourse about 10 days before and after ovulation, still get pregnant unexpectedly.

Why is this? It turns out that female ovulation is controlled by nerves and endocrines. When the spirit is overexcited, nervous, the living environment changes or the physical health status changes, the ovarian ovulation will be affected, resulting in non-ovulation ovulation, which is called extra ovulation. Women who are newly married or reunited with their husbands after a long separation are most likely to have extra ovulation, so they should pay attention to contraception.

Even if you strictly follow the requirements and regulations for safe period contraception and avoid sexual intercourse about 10 days before and after ovulation, you will often get pregnant unexpectedly, and the failure rate can be as high as 15%. What is going on? It is mainly due to the occurrence of extra ovulation.

Because ovulation is dominated and controlled by nerves and endocrine, when the spirit is overly excited, nervous, the living environment changes or the physical health is not good, etc., it will affect the ovarian ovulation. The most obvious example is newlyweds, who have strong sexual desire and are easily excited. In the war years, soldiers who came home from the battlefield to visit their families, and couples who reunited after a long separation on business trips, because of the high excitement of the sexual center of "a short separation is better than a newlywed", the ovaries were stimulated and "extra ovulation" occurred, which caused unexpected consequences, and the safe period was not so safe.
