What Is Adolescent Pregnancy?

To increase the chance of conception, it is necessary to master the conception period of women; menstrual cramps appear on the 14th day after ovulation, and this time interval is relatively constant, independent of the change in the length of the female reproductive cycle. According to this rule, it is possible to predict at what time in each reproductive cycle it is possible to conceive, which is the conception period. Sperm can survive in a woman's reproductive tract for 72 hours, while eggs can only be fertilized within 12 to 24 hours after ovulation. Therefore, sexual intercourse that occurs within 3 days before ovulation and within 1 day after ovulation occurs may cause pregnancy, because during this time, there is a great chance that sperm will meet the discharged egg in the woman's fallopian tube, thereby fertilizing the egg. .

Conception

Ring wearers: It is not advisable to conceive immediately after taking out the contraceptive ring, and the endometrium needs to be completely restored in tissue and function, that is,

Avoid the two major black fertility periods

The so-called "black" conception time means that the sperm and egg meet in a poor physiological state of the human body or in a poor natural environment to form a fertilized egg. Such fertilized eggs are susceptible to various interferences and their quality is affected.

Black fertility time 1: conception during low tide time

Scientific research shows that from the time of birth to the end of life, there are cyclical changes in the physical, emotional, and intellectual aspects of the body. This periodic change is the physiological rhythm of the human body.

When the human body is at the low tide of the circadian rhythm or the critical day of the low tide and the high tide, the body is prone to fatigue, emotional instability, low efficiency of work, difficulty in concentration or forgetfulness, and decreased judgment. At the same time, the body's resistance is reduced, it is easy to be invaded by germs, and the probability of infection is increased. During pregnancy, if one spouse is at orgasm and the other is at low tide, it is easy to give birth to children with normal health and intelligence; if both spouses are at low tide or the threshold between low tide and high tide, it is easy to give birth to children with weak and mental problems.

Avoid Black Fertility Time Tips:

1. Find out the climax time of the circadian rhythm of both spouses. Generally speaking, the period of physical circadian rhythm is 23 days, the period of emotional circadian rhythm is 28 days, and the period of intellectual circadian rhythm is 33 days. Each circadian rhythm has a high tide period, a critical day, and a low tide period. The critical day refers to the middle day of each cycle, which is the critical time of low tide and high tide. The critical days of the three physiological cycles are 11.5 days, 14 days, and 16.5 days. The first half of the critical days is the high tide period, and the second half is the low tide period. If the couple can conceive during the climax of the three rhythms, the child is often healthy and intelligent.

2. The human body rhythm cycle can be calculated by perpetual calendar. The calculation of the human circadian rhythm is the total number of days from the day of birth until the day of conception, plus the number of days added in the leap year. Then, divide the three numbers 23, 28, and 33, respectively, and you can know which phase of the three rhythm cycles the body is in. The days when the remainder is equal to the critical day are the critical days, the remainder is less than the critical day as the high tide period, and the remainder greater than the critical day is the low tide period.

Black conception time 2: conceive when you are physically or mentally impaired

Studies have confirmed that when husbands and wives are not tired and emotionally happy to conceive in the same room, this state of good body and mind will cause the endocrine system to secrete a large amount of enzymes, hormones, and choline acetate, which are good for health. The strength and intelligence of both spouses are in the best condition. At this time, sexual function is the most harmonious, it is very easy to enter orgasm and form excellent fertilized eggs.

On the contrary, the tiredness or bad mood of both spouses or one of the spouses will affect the vitality of sperm or eggs, and will not be conducive to the formation of excellent fertilized eggs, and will affect the implantation and growth of fertilized eggs, leading to fetal wilt, miscarriage or affecting the fetal brain nerve development.

Avoid Black Time Tips:

1. A few days before preparing to conceive, both husband and wife must pay full attention to physical rest and relax. At the same time, it is best to stop sex for 5-7 days to ensure sperm vitality.

2. Before preparing to conceive, do not have frequent sexual life, or sexual sparse life, which is not conducive to conception. Excessive frequency will make the semen thin and the number of sperm small; too thin will make the sperm aging and poor vitality.
