1 and the test method of ovulation date
You can guide contraception and pregnancy according to your actual situation.
I. Aquino Act
Aquino method is also called mathematical formula method, that is, from the last day of menstrual cycle (that is, the first day of next menstruation), the ovulation date is pushed forward by 14 to 15 days. If the day of the next menstrual cramp is the nth day, then the ovulation day this time is the nth-14th day. Although the length of menstrual cycle varies from person to person, the life span of luteal phase of most people is 14 days, which is constant. The change of menstrual cycle is caused by different follicular phases. So we can simply predict the date of ovulation with mathematical formula.
For example, from the perspective of contraception, every menstrual cycle of women can be divided into menstrual period, ovulation period and safety period. The ovulation date of women is generally about 14 days before the next menstruation, and 5 days before and after the ovulation date, including *** 10 days, which is called ovulation period. For example, this menstrual period comes on the 29th, and the ovulation date is on the 5th of this month, and the ovulation period is from the 9th of this month to the 9th of this month.

Expert summary: This method of detecting ovulation day is rarely used, and some female friends will choose this method, but most women think the process is complicated.
Second, cervical mucus method
Cervical mucus will appear throughout the menstrual cycle, and there are slight periodic changes. We know that endometrial gland cells in the cervix can secrete mucus, and the secretion amount and physical and chemical properties of mucus have obvious periodic changes. Just after menstruation, mucus secretion gradually increases, gradually becoming thin and transparent, similar to egg white, reaching a peak before ovulation. It can also be said that the day with the most mucus has the highest probability of ovulation. At this point, put your finger into the depths of the female private parts and touch some mucus flowing from the cervix, which can be drawn into filaments as long as 10 cm. After ovulation, under the action of progesterone, mucus secretion is obviously reduced, sticky and turbid, with poor ductility and easy to break when drawing. If you observe and record the state of mucus every night and understand the changing law of mucus, it is easy to find your own ovulation day.

Expert summary: Some female friends will use this test method of ovulation day. After all, this method can take a quiz before a woman takes a shower, shares a room, changes clothes or goes to the toilet. This method is simple and feasible.
Third, the intermediate pain method
Some people feel abdominal pain in the middle of two menstrual periods, just equivalent to the time before ovulation, which is called intermediate pain or ovulation pain. According to an expert survey, 97% of intermediate pain is felt before ovulation. Therefore, if there is intermediate pain, ovulation can be considered within 24 hours.
User recommendation: ★★★★
Expert summary: This detection method of ovulation day is chosen by female friends, because there will be slight abdominal pain during each menstrual period. You can still feel it if you distinguish it carefully. For some people, this method may be the simplest and easiest. The disadvantage is that a small number of people have no intermediate pain and cannot use this method.
Fourthly, basal body temperature method.
The so-called basal body temperature refers to the body temperature when you wake up in the morning, your body is quiet and your mood is calm. During menstrual cycle, basal body temperature changes periodically. The basal body temperature is low after menstruation and follicular phase, and corpus luteum is formed in the ovary after ovulation. The progesterone produced acts on the hypothalamic thermoregulatory center, raising the body temperature by 0.3-0.5℃, and it will not drop to the original level until 1-2 days before menstruation or the first day of menstruation. Because people's body temperature will change for some reasons, it is necessary to have a normal life rule when measuring, sleep for more than 6 hours every day, and the measurement time is roughly the same every day.
Specific methods: throw the thermometer under the scale before going to bed every night, wake up the next day, don't talk, pick up the thermometer and put it under your tongue for five minutes. It should be counted from the first day of menstruation (that is, the day when menstrual cramps occur). Record the temperature measured every day and make a basic thermometer. You can also go to the hospital to buy a special basic thermometer and mark the temperature one by one according to the instructions. In normal menstrual cycle, the basal body temperature measured every day is drawn as a line, showing a biphasic curve. If there is no ovulation, the basal body temperature shows a monophasic curve, and there is no increase or change. Women who ovulate normally should continue for 12- 14 days after their body temperature rises. This form is very useful. It can be used to guide contraception and pregnancy, help diagnose pregnancy and help diagnose menstrual disorders. Ovulation can be confirmed after 4 days of basal body temperature rise, and the period from this time to 10 day before menstrual cramps is called the safety period. The ovulation period is 2-3 days before and after the basal body temperature rises, and it is easy to get pregnant, which is called easy pregnancy. Mastering this law can guide contraception and pregnancy well.

Expert summary: This test method of ovulation day is chosen by female friends, but it is too complicated and not practical for white-collar workers in Beijing. It's a long way to work, so there is not enough time to take their temperature. It is also a reason that cannot be ignored, and fewer people choose.
Five, ultrasonic examination method (female private parts B ultrasound detection of ovulation)
At present, all major hospitals in China observe the size of ovary, determine the size of follicle and infer when ovulation period is. Follicles are generally about 2-3 mm, and will gradually increase near ovulation day, reaching 18 mm two days before ovulation day, and increasing to more than 20 mm on ovulation day. If the observation day happens to be the day of ovulation, sometimes follicular rupture can even be seen on ultrasound. Therefore, vaginal ultrasound is the most direct and accurate method to detect ovulation. First of all, we can use menstrual cycle method to predict an approximate ovulation date, measure follicles on the day close to ovulation date, observe the size of follicles and seek the guidance of doctors. If the follicle has just formed or is still very small, you can do an ultrasonic examination every two days to monitor the growth rate of the follicle. When the follicle is close to maturity, it is about 16 mm, and it can be checked every day, even twice a day, until the follicle is mature. After ovulation in follicular rupture, ultrasound can find a small amount of accumulation in the pelvic cavity, which confirms the success of ovulation. If you can cooperate with the basic thermometer, secretion viscosity test and mid-term pain method, you can basically determine the date of ovulation very accurately, then your chances of pregnancy will be greatly increased.

Expert summary: This detection method of ovulation day is relatively accurate, but it is expensive and troublesome, and it is difficult to insist on a series of things such as asking for leave, counting the date and registering.
Waiting in line with urine is easy to be agitated or affect the quality of eggs.
Hospitals generally provide B-ultrasound to monitor follicles, including female private parts and abdomen. If you do abdominal B-ultrasound, you need to hold your urine beforehand. Although it usually takes only a few minutes to monitor follicles by B-ultrasound, it may take more than an hour to queue up to monitor follicles in some overcrowded hospitals.
"Although B-ultrasound monitoring eggs has no side effects, it is not particularly necessary for normal women to do this examination." Experts remind that the B-ultrasound monitoring of eggs can not be completed at one time. You need to do it several times a month, and you have to register and queue up every time. If the mood becomes irritable, the quality of eggs will be bad.
"Pregnancy is a natural process. Deliberate intervention is unscientific. The more anxious you are, the more likely you are to get pregnant. " Experts suggest that women who want to do B-ultrasound monitoring of eggs must go to a regular hospital under the guidance of a doctor.
Six, ovulation test paper
Detection principle: In every menstrual cycle of women, the luteinizing hormone (LH) in urine will reach its peak within 24-48 hours before ovulation, and the peak level of LH can be accurately detected by ovulation test paper. After the detection is started, it will be detected regularly every day, and when the color close to the peak appears, it will be detected every 12 hours until the LH peak is detected. Because each woman's menstrual cycle days are different, you can refer to the cycle test table when testing.
Usage: 1 Collect urine in a clean and dry container. Morning urine must not be used. (Remember) 2. The best time to collect urine is from 10 to 8 pm. 3. Try to use urine samples at the same time every day. 4. Water consumption should be reduced within 2 hours before urine collection, because the diluted urine sample will hinder the detection of luteinizing hormone (LH) peak. 5. Take the test paper and immerse one end with the arrow mark line in the urine, take it out and lay it flat after about three seconds, and observe the results 10-20 minutes. The results should be read within 30 minutes. The liquid level shall not exceed the maximum line. 6. It is best to have an examination on the third day after menstruation is clean. Take an exam every day. You can't use the morning urine test. Until the two bars are as deep as the first bar or the second bar is deeper than the first bar, it means that you will ovulate within 24-48 hours, and it is possible to get pregnant in the same room from 3 days before ovulation (eggs such as sperm) to 3 days after ovulation (eggs such as sperm). If you measure two bars, you can have the same room on the day of ovulation, and then have the same room every other day. (Because sperm can live for 48-72 hours)
User recommendation: ★★★★★
Expert summary: Many female friends choose this detection method of ovulation day. It should be that if used correctly, the test accuracy may be close to 100%, and the cost is low, so it is an ideal choice for female friends.
2. Changes of female ovulation period
Unless you take hormonal contraceptives, a woman's body will ovulate every month, and there will be the following subtle physiological changes every month.
anorexia
Studies have shown that women's appetite during ovulation is the lowest in a menstrual cycle, and experts point out that this is the result of human natural instinct preserved so far-female animals during ovulation will pay more attention to finding similarities and differences than looking for food.
powerful
This is also inherited the natural instinct of mankind. In order to attract the opposite sex successfully, ovulation women will become radiant and love to express themselves.
Have a high desire
Generally speaking, women's desire during ovulation will be particularly strong, which is the highest level of women's desire to get pregnant.
Decreased resistance
During ovulation, the mucus in women's private parts will become thinner, which is to make it easier for sperm to pass through, thus increasing the chances of successful pregnancy. At the same time, the mucus in the female nasal cavity will also decrease, which increases the chances of bacteria invading the human circulatory system.
3. Women should pay attention to ovulation.
First, be cheerful and avoid mood swings.
Women will experience certain fluctuations in hormone levels during ovulation, which may affect women's emotional health. On the other hand, emotional changes can also cause changes in women's endocrine. Therefore, women should keep cheerful during ovulation and avoid being too depressed and irritable to ensure the quality of eggs and carry out healthy pregnancy.
Second, protect the nasal cavity and avoid respiratory tract infection.
When women ovulate, mucus in the nasal cavity will be reduced, and bacteria in the air will enter the respiratory tract more easily than usual, causing respiratory infection. Therefore, special attention should be paid to prevent respiratory tract infection during ovulation.
Third, eat healthily and avoid irritating food.
During ovulation, estrogen will drop sharply in a short time, and a small amount of endometrium will fall off. Therefore, the diet at this time should not be over-stimulated to protect the health of the uterus. In principle, the diet during ovulation should be based on high nutrition and high protein, and spicy, irritating, greasy and cold foods should be avoided. In addition, you can take vitamin E properly and eat more beans, milk and other foods to supplement the deficiency of estrogen and maintain ovarian function.
Fourth, live a regular life and avoid excessive fatigue.
Ovulation is the same as menstruation, and women should learn to protect themselves. Keeping a regular life is the first step to ensure health, especially modern women should learn to relax themselves, combine work and rest and avoid overwork during ovulation. Severe fatigue will affect the normal ovulation function of ovaries, leading to a decrease in pregnancy rate.
Pay attention to hygiene and avoid bacteria and lovely dyes.
During ovulation, the cervix is slightly open, and the mucus in women's private parts will become thinner, mainly to facilitate the entry of sperm. So on the other hand, the resistance to bacteria during ovulation is relatively weak, so reproductive health should be done well during ovulation. For example, change underwear frequently and choose comfortable pants.
