Nowadays, many people want to plan their pregnancy, so they are concerned about how to calculate ovulation and which day is the day of ovulation. How can you make your baby arrive on time? In women of normal reproductive age, an egg matures and ovulates every month, and the sperm unites with this ovum and moves to the uterus to develop into a fetus. However, the egg is only viable for 24 hours, so how can we know exactly when we are ovulating? Of course there are many advanced methods to detect ovulation in hospitals nowadays, but they cost a lot of time and money. Now I will introduce you three simple methods to predict ovulation. 1, the basic body temperature method: every morning after waking up without doing any activity, lying in bed to try the mouth table, the daily measured body temperature drawn on the temperature list. The basal body temperature is low before ovulation, and then drops by 0.1~0.2℃ when ovulation occurs, and immediately rises by 0.3~0.5℃ after ovulation until the menstrual period, and will continue at this level after conception. If you want to conceive during ovulation, it is best to have intercourse within 24 hours of the lowest temperature for the highest conception rate. 2.Menstrual cycle method This method is for women with normal menstrual cycle, the ovulation day is relatively fixed, it should be about 14 days before the next menstrual period, for example, this period is on July 1, next month should be August 1, the ovulation day will be about July 16. For women with irregular menstruation, this method is not so easy to grasp, so we have to rely on the basal body temperature measurement and observation of the leukorrhea to estimate. 3, leucorrhoea change method Under normal circumstances, the quality and quantity of leucorrhoea changes with the menstrual cycle. Just after the menstruation, the leucorrhea is white in color, small in quantity and paste-like. When ovulation is imminent in the middle of menstruation, the leucorrhea increases due to the vigorous secretion of the cervical glands, which is transparent, slightly sticky and egg white like and can be stretched to about 10 cm. Two to three days after ovulation, the leucorrhea becomes cloudy, sticky and low in volume. How to do it: Wipe the vaginal opening with your hand and observe the transparency, amount and lengthening of the mucus on the hand paper (slowly stretch the mucus on the hand paper with a blank hand paper), the peak day of mucus usually occurs 2 days before to 3 days after ovulation. The vulva will also self-feel from dry to moist, and finally for slippery then for ovulation. In modern medicine, the ovulation period has long been discussed in traditional Chinese medicine, that is, the “dense time”, the creatures of heaven and earth, there must be a dense time, all things are born, there must be a time of joy. Danjing” cloud: January stop a day, a day stop a time. Where a woman’s menstrual cycle once a month, there must be a day of dense, in an hour, steam and hot, faint and stuffy, there is a desire to meet the unbearable state, this is also the waiting. At this time, the reverse is taken into Dan (must be taken against the way, to be is to build the foundation, this first weather is born), and the application of the Shun is into fetal carry on. Chinese medicine believes that, after about half a month after the net, the Yin essence gradually filled, the essence into gas, Yin turned into Yang, is an important transformation in the menstrual cycle, Yang Qi suddenly flourished, the dense shape of the sprout, marking the arrival of ovulation.
