(1) Prediction method
The first day of ovulation = the shortest menstrual cycle Number of days – 18 days Last day of ovulation = longest menstrual cycle days – 11 days
Calculation method: If through observation, menstruation is very regular, once every 28 days, then you can calculate the menstrual cycle The maximum number of days and the minimum number of days are both set at 28 days. Substituting into the formula, your \”ovulation period\” can be calculated as: the 10th to 17th days after your menstrual period. This calculation method uses the first day of the current menstrual period as the base point and counts the days backwards, instead of using the next menstrual period as the base point and counting the days backwards, so it is not easy to make mistakes. After finding out the \”ovulation period\”, if you want to get pregnant, you can start from the first day of the \”ovulation period\” and have sexual intercourse every other day for several months, and you are very likely to get pregnant. If you don\’t want to get pregnant, you have to miss the \”ovulation period\” and have sex. Since the ovulation period will be affected by disease, emotion, environment and drugs, it must be used in conjunction with other methods.
(2) Measure basal body temperature
Basal body temperature is It refers to the body temperature measured after 6 to 8 hours of sleep before the body temperature has been affected by exercise, diet or emotional changes. The day of ovulation can be calculated by recording basal body temperature.
Under normal circumstances, the basal body temperature of women of childbearing age gradually decreases before ovulation, which is relatively low and remains at 36.4~36.6℃; after ovulation, the basal body temperature rises, generally by 0. 3～0.5℃ for 3 days. From 3 days before ovulation to 1 day after ovulation, this period is the fertile period and can be used as a reference for pregnancy planning.
Swing the thermometer below 35℃ every day before going to bed and put it in a safe place beside the bed. Do not do any activities when you wake up the next day and measure your temperature immediately, because any movement may cause the body temperature to rise. Error occurs due to rising, so the measurement must be completed while inactive. It is necessary to continuously measure and record for at least 3 months and draw a curve chart in order to grasp the rising and falling patterns of body temperature and determine your ovulation day.
TestPay attention to basal body temperature
Those who have difficulty taking their temperature in the morning can take their temperature at a fixed time every day , remember not to exercise vigorously or drink hot or cold food half an hour before the measurement.
Although the method of measuring basal body temperature is simple, it is strict and requires long-term persistence. Generally, more than 3 consecutive menstrual cycles need to be measured to explain the problem.
During the menstrual period, if you have a cold, fever, diarrhea, insomnia, drinking alcohol, using an electric blanket, etc., it is often easy to affect the basal body temperature. You should pay attention when measuring and mark it with special instructions.
Be sure to record your basal body temperature every day. If you forget to measure it one day, you can make a rough inference based on the previous records. However, do not be lazy or take chances, otherwise the records will be inaccurate. Lost the purpose.
Make your own basal body temperature chart
①The abscissa is the date, One square per day, a total of 35 squares. If your menstrual cycle is relatively long, you can do 5 to 10 more squares.
②The ordinate is body temperature, which can start from 35.5℃ and gradually increase from bottom to top, with one step every 0.1℃, up to 39℃ which is enough.
③At the bottom of the abscissa, leave a little more blank space for notes to record events that have an impact on body temperature that have occurred on the corresponding days, such as drinking, catching a cold, being nervous, staying up late, taking medication, etc. At the same time, sexual intercourse should be marked with markers.
④ Wake up every morning, measure your body temperature before doing any activities, mark it on the record sheet, and draw the temperature change curve to form the basal body temperature curve. Put the thermometer in your mouth for at least 5 minutes, take out the thermometer, observe the temperature, and mark the corresponding position on the table.
⑤ Generally start measuring and recording body temperature on the 5th day of the menstrual cycle.
(3) Observe cervical mucus
According to vaginal mucus To determine the day of ovulation, a woman\’s menstrual cycle is divided into \”dry period – wet period – dry period\”. During the wet period in the middle of menstruation, leucorrhea is more abundant and unusually thin, usually lasting 3 to 5 days. Observe that the vaginal secretions are like egg white, clear, transparent, highly elastic, and long. This is the day of ovulation.
After menstruation, cervical mucus is often thick and less abundant, which is called the dry period, indicating a non-ovulatory period. In the middle of the menstrual cycle, mucus increases and becomes thinner, and vaginal secretions increase, which is called the wet phase. Close to ovulation. The mucus becomes clear, smooth and elastic, like egg white, highly stringy and not easy to break.The 48 hours before and after the last day when this mucus appears is the ovulation day. When the vagina feels moist, it is the ovulation period, also known as the fertile period. If you plan to conceive, you should choose the wet period before ovulation.
Application Points
① Observe cervical mucus several times a day. Generally, you can use your fingers to take the mucus from the vaginal opening after getting up, before taking a bath or before urinating. You can observe the appearance and viscosity of the mucus on your fingers and do a string test with your fingers.
② Focus on observing the tendency of mucus from thick to thin. Once the mucus can stretch to several centimeters, it should be considered to be in the fertile period (ovulation period).
③The cervical mucus method is also suitable for women with irregular menstruation to control their ovulation period.
Notes
①Be sure to wash your hands before observing cervical mucus clean.
② When there was no sexual intercourse the night before, the observation results were more accurate.
③ Observing cervical mucus requires experience, and you should practice for 2 to 3 months to make a more accurate judgment.
④The changes in cervical mucus in the vagina are affected by many factors, such as severe vaginal infection, vaginal douching, vaginal secretions during sexual excitement, mucus after sexual intercourse, and the use of intravaginal spermicidal drugs.
⑤ When judging the characteristics of leucorrhea, it should be distinguished from the pathological increase in leucorrhea caused by various vaginitis. In the latter, the leucorrhea can be yellow pus-like, lumpy, yellow soapy water-like, often smelly, and can also be accompanied by Symptoms such as extreme itching of the vulva need to go to the hospital for treatment.
(4) Test with ovulation prediction test paper
First Determine the usual menstrual cycle, that is, the number of days from the 1st day of each menstrual period to the 1st day of the next menstrual period, starting from the 11th day of the menstrual cycle and testing once a day. Home self-tests can be carried out in order to arrange family planning and elective pregnancies.
