One of the most interesting questions for expectant mothers is how to determine ovulation, because the chances of successful conception are greatly increased when you have intercourse around the time of ovulation, so let’s talk about some tips on ovulation. We all know that new life begins when a mature sperm and an egg become one. Mr. Sperm has hundreds of millions of newly matured ones every day, and the growth and maturation cycle of a sperm is only 76 days. However, the egg lady only matures 1-2 per month and is characterized when the expectant mother herself is still an embryo and gradually ages at any time. Therefore, the key to conception is for the winner among the sperm gentlemen to have a perfect encounter with the egg lady when she comes out of the court. A normal menstrual cycle is 28±7 days. The date of ovulation is usually about 14 days before the next menstrual period. Usually we refer to the 5 days before and 4 days after the ovulation date, together with the day of ovulation, a total of 10 days as the ovulation period. The egg lady can survive in the fallopian tube for 1 to 2 days after being expelled from the ovary to wait for fertilization. Mr. Sperm can maintain his fertilization ability in the female reproductive tract for 2 to 3 days, so it is easy to conceive during intercourse in the days before and after the egg is discharged. 2.Methods to determine ovulation: Simplicity Cervical mucus * Basal body temperature ** Ovulation test paper *** B ultrasound **** Accuracy Cervical mucus * Basal body temperature ** Ovulation test paper *** B ultrasound **** 3：Methods to monitor ovulation in practice 1.Cervical mucus (discharged through the vagina, we are commonly called “leucorrhea”), during ovulation The secretion will increase, become thin and even pull out a long silk (more than 8cm is close to ovulation).

Evaluation: This is a change in the body that can be detected by a careful mother who pays a little attention and does not need any auxiliary tools. 2. Basal body temperature The body temperature is taken at the same time every day after waking up (after 6 to 8 hours of rest), lying in bed without any activity and without talking, by placing the thermometer under the tongue for about 5 minutes. Before moving from the low temperature phase to the high temperature phase, the basal body temperature drops to a minimum point – the day of minimum temperature. Most women ovulate around this date. It is necessary to take measurements continuously for 3 months and record them on a special form to clarify the day of minimum temperature. Sexual intercourse three days before and three days after the day of minimum temperature can increase the chances of pregnancy. Evaluation: Time consuming and requires patience. 3.Ovulation test paper Test time: between 10:00 am and 8:00 pm.
