Some people strictly follow the ovulation day and deliberately pursue the same room on the ovulation day. High demands and high expectations will cause psychological pressure on both husband and wife, making people nervous, thus reducing the chances of pregnancy. In fact, the young couple should have a better attitude and try to let nature take its course. As the saying goes, you can't eat hot tofu if you are impatient, so don't worry too much, otherwise these anxieties are likely to lead to endocrine disorders.
You can't have sex too often, and you can't do whatever you want. Usually, husband and wife should live regularly, stipulate several times a week, and appropriately increase ovulation period, which can improve sperm quality and increase the possibility of successful pregnancy.
There are no good living habits, especially young people nowadays, who often stay up late, have rich nightlife, some even stay up until five or six in the morning, have no regular work and rest, don't eat three meals on time, lack the concept of scientific diet, and have no regular physical exercise at ordinary times, which are easy to affect pregnancy.
Finally, there is a key point, that is, the couple's genes are not harmonious, that is, the chromosomes of the two sides are different. This is a congenital reason, which can't be found by general physical examination. If we want to rule out this reason, we need to go to the hospital for genetic testing.
