In order to increase the probability of pregnancy, women who prepare for pregnancy usually choose to prepare for pregnancy during the ovulation period. How can they know exactly when their ovulation period is? Today I will introduce some current scientific ovulation plan.

排卵期是怀孕的最佳时机,很多怀孕夫妇都错了!

Menstrual cycle calculation


Ovulation occurs 14 days before the next menstruation, that is, the menstrual cycle minus 14 days is the ovulation period.


If 28 days is a menstrual cycle, then 14 days after menstruation (28-14 days=14 days) is the ovulation period;


If 32 days is a menstrual cycle, then 18 days after menstruation (32-14 days=18 days) is the ovulation period.


This method is simple and convenient to operate, but it is not suitable for a woman with irregular menstruation, and ovulation may occur earlier or later due to the influence of environment, mood, etc. It is also unreasonable. It is also very unreliable to analyze and calculate the safety period as a contraceptive method.


Basal thermometry


The basic temperature is measured from the first day of menstruation. The basic temperature is measured under the tongue every morning (5-7 o'clock), and the temperature changes are recorded.


Under the effect of progesterone, the central body temperature rises after ovulation, and the basal body temperature rises by 0.3 ℃ - 0.5 ℃ for 12-14 days, that is, the biphasic body temperature changes.


This method is simple and easy to operate, but it needs to be measured at the same time every day. It requires strict requirements for no exercise, no defecation, no urination, etc. before measurement to prevent inaccurate measurement from affecting the judgment of results.

Changes of cervical mucus


During ovulation, female vaginal secretions become thin, like egg white, and stretch long.


Women can judge whether they are ovulating according to the changes of cervical mucus, but some women have no obvious changes.


Determination of progesterone level


The level of progesterone in serum increases 6-7 days after ovulation, so the change of progesterone and progesterone can be detected in the second half of the menstrual cycle. If ovulation occurs, it will increase.


This method is more accurate, and can also judge the luteal function, but blood sampling is required.


B ultrasound monitoring ovulation


At present, the most commonly used method is to monitor the growth and development of follicles with urine LH measurement and vaginal ultrasound to observe whether ovulation occurs.


Generally speaking, women with normal ovulation will develop a dominant follicle every month and discharge a mature egg.


Expert tips


In fact, the ovulation time of women is not completely fixed.


The ovulation period is easily affected by the external environment, climate, sleep, emotional changes, quality of sexual life, health status and other factors, so that the ovulation period is delayed or advanced, and even additional ovulation may occur.
