The so-called black conception of time, is the sperm and eggs in the body of poor or adverse physiological state of the natural environment, meet to form a fertilized egg. Such eggs vulnerable to all kinds of interference, the quality affected. Pregnant women to succeed to the best pregnant women need to master time, to avoid the black time to pregnancy.
1: low in human circadian rhythms in the conception of time
Human circadian rhythm at low tide or low tide and high tide of the critical day, the body is easy fatigue, and mood swings, low work efficiency, difficulty concentrating or forgetfulness, poor judgment. Meanwhile, the body defenses are weakened and susceptible to bacteria infestation, increased risk of infection. Pregnancy, if the spouse at its height, the other at a low ebb, easy to give birth to healthy children in general and mental condition; if both spouses are at low tide or low tide and high tide of critical, is easy to give birth to weak, mental problems of children.
2: The number of physical and mental well or the same room when the pregnancy is not appropriate
Study confirmed that both husband and wife in the body is not happy when the fatigue and emotional intercourse carefree pregnancy, this state of mind and body is superb, makes a lot of healthy endocrine system secretes enzymes, hormones and acetylcholine, so that the couple's physical strength, mental state at best. At this time, the most harmonious sexual function and very easy access to sexual climax, the formation of good eggs.
On the contrary, the body either one or both spouses feeling tired or ill, will affect the vitality of the sperm or egg, fertilized egg is not conducive to the formation of the fine, and implantation of the fertilized egg and growth, leading to fetal wilt, miscarriage or affect fetal brain of development.
3: do not pay attention to his wife when conception orgasm
Experts point out that in the sexual life of women reach orgasm is not conducive to the formation of good eggs. Because the sperm in the vagina orgasm will exercise capacity increased in the same time easy storage of semen in the vagina, cervix atresia will promote relaxation of open, easy-to-sperm. As a result, the more strong and excellent combination of sperm and egg have the opportunity to form a zygote good.
4: the natural environment in the poor pregnancy
The human body is a conductor full of electromagnetic fields, natural environment, such as solar magnetic storms, thunder and lightning, landslides, earthquakes, Solar and Lunar Eclipse, will all affect the body's reproductive cells, such as causing distortion, so in these times are not pregnant. Otherwise, easy birth an unhealthy child.
In addition, the experts pointed out that menstrual cramps in the first 14 days after ovulation, this time from the length of the female reproductive cycle of change. The majority of women can be expected according to the laws of the reproductive cycle in which each period is the best time to pregnancy.
Ready to learn to self-test ovulation pregnancy
First, Aquino Law
Aquino, also known mathematical formula method, from the last day of the menstrual cycle (that is, the first day of next menstruation) to push ahead 14-15 days is the ovulation day. If the next menstrual cramps the day for the first N days, then this ovulation is the first N-14 days. Although the length of the menstrual cycle is different for each person, even if the same person are not the same length of each cycle, but most of the life of the luteal phase is 14 days, which is constant, changes in menstrual cycle is different because the follicular phase caused. So we can use a simple mathematical formula predicting ovulation day.
Tips: This test method ovulation, less people use, but there are also individual female friends would choose such a method, but most women process is too cumbersome and complex.
Second, the cervical mucus method
Cervical mucus throughout the menstrual cycle will appear, and it has a subtle cyclical changes. We know that the endometrial glandular cells cervical mucus, mucus secretion and its physical and chemical properties have significant cyclical changes. Right after menstruation, mucus secretion is also increasing, and gradually becomes thin and transparent, similar to egg white, reached the peak before ovulation, it can be said that the largest amount of mucus a day, the highest probability of ovulation. At this point, deep into the vagina with your fingers, dip some of outflow from the cervical mucus, mucus can be pulled into a 10 cm long and continuous filaments. After ovulation, the role of progesterone, the mucus secretion was significantly reduced, thick and muddy, poor scalability, easier to fracture when drawing. Understand the variation of mucus, if mucus every night of the state were observed and recorded, you can easily find your ovulation.
Tips: This ovulation test methods will be used for individual female friends, after all, this method can take a bath in the female, before the same room, change clothes, or empty the toilet what can be done when a small test. Method is simple and easy to operate.
Easy to conceive type of cervical mucus: a few days before ovulation, estrogen further increase in water content of cervical mucus more and more brighter, such as egg-shaped, the minimum viscosity, smooth and elastic, with the thumb and index finger can be pulled into the mucus long filaments (up to 10 cm or more), then obviously the vulva feels moist feeling. Clear transparent secretion was generally believed that the egg-shaped, drawing level is likely to be the longest day of ovulation, in this day and 3 days before and after ovulation. After ovulation, corpus luteum formation and progesterone production, thereby inhibiting the cervical mucus, cervical mucus and therefore fewer and sticky, not easy to conceive a type of cervical mucus, until the next menstrual cramps. Next month menstrual cycle the cervical mucus and the changes occur.
Third, in the middle pain method
Some people in the middle two periods, just equal to the time before ovulation, the feeling of pain in lower abdomen, known as the middle of pain or ovulation pain. Experts have been investigated, 97% of the middle of the pain is felt before ovulation, and therefore, if the middle of pain, you can believe that ovulation will occur within 24 hours.
Tips: This test method ovulation, a woman friend choice, because in each menstrual period to complete, there will be a slight feeling of abdominal pain, and if careful to distinguish, or to feel, this method for some people , may be the most simple way, the disadvantage is not a small number of people among pain, can not this method.
Fourth, basal body temperature method
The so-called basal body temperature refers to the morning, the body to keep quiet, calm mood in the state of the body temperature. In the menstrual cycle, basal body temperature changes periodically. In the menstrual follicular phase and after low basal body temperature after ovulation due to ovarian corpus luteum formation, progesterone produced in the hypothalamus thermoregulatory center, so that the temperature rise 0.3-0.5 ℃, until by the former 1 - 2 or the first day of menstruation, body temperature dropped to the original level. As the human body temperature will change for some reason, so determined, it must have normal patterns of life, the daily sleep should be maintained at more than 6 hours, and the measurement time to about the same day.
Tips: This test method ovulation, a woman friend option, but this method is too cumbersome, body temperature every day, recording, contrast, white-collar workers for the Beijing family is not practical, long way to go to work, crowded bus to get up early, not have sufficient time to body temperature, is also an important reason, choose to be less.
V. Detection of ovulation vaginal B-
At present, the major hospitals vaginal ovary the size of the B-observation to determine the size of follicles, the presumption is when ovulation. Follicles about 2-3 mm under normal circumstances, when close to ovulation, increases in the 2 days before ovulation, up to 18 mm, ovulation day will increase to 20 mm. If you happened to be observed at ovulation, and sometimes even see the ultrasound follicle rupture. Thus, the use of transvaginal B-detection of ovulation is the most direct and most accurate method.
Tips: This test method ovulation, more accurate, but expensive, and too much trouble, leave, counting the days, registered a series of things, very difficult to stick with it to the hospital for monitoring.
VI, ovulation test strips
Test principle: in the female monthly menstrual cycle, urinary luteinizing hormone (LH) 24-48 hours before ovulation will occur within the peak value, the use of ovulation test strips can be more accurately detect the LH peak level. Post-test should begin regular testing day, when there will be close to peak color should be tested once every 12 hours until the detected LH peak. Because each woman's menstrual cycle days different reference period can be detected Checklist.
First, ovulation test strips to hold the arrow signs will be immersed in one end of the line to their own urine, about three seconds before removing the flat, and another 10-20 minutes of time to observe the results, generally results within 30 minutes Read prevail. The best time to collect the urine of women are generally 10 am to 8 pm this time.
Ovulation test strip resulted in a two purple lines: the bottom line (test line) than the top line (control line) was light, said the urine LH peak has not yet appeared. Not to ovulation, there are two purple lines. , The bottom line (control line, test line) is basically the same color, or the bottom line (test line) than the top line (control line) dark, said it would ovulate within 24-48 hours.
Tips: This test method ovulation, the women have more choice, it is possible to test the accuracy of close to 100%, but costs are low, is an ideal choice female friend method.
Seven in urine method
Under the guidance of a doctor can monitor the follicular B-, when the follicle of 1.8 cm, the measured urinary LH, 2-4 hours each time, there can be considered to fall peak urinary LH peak. After the peak ovulation within 12-24 hours. If you can not monitor the follicles, can be combined with the previous menstrual cycle, two days before the expected ovulation, the measured urinary LH, start interval time can be larger, when the urinary LH was significantly increased, you can monitor the time interval of 2-4 hours.
