The probability of getting pregnant is relatively high during the fertile period if both the man and the woman are in good health. However, it is not true that you can get pregnant during the period of pregnancy, but whether or not you can get pregnant is related to a number of factors. The easy period of time is clinically known as the ovulation period, with the development of the follicle maturity, the follicle gradually to the surface of the ovary and protruding outward. When the follicle approaches the surface of the ovary, the surface cells there become thin and finally rupture, and the egg cell is discharged after most of the follicular fluid has flowed out, which is called ovulation. If the menstrual cycle is usually accurate, the date of ovulation is usually about 14 days before the next menstrual period, 5 days before and 4 days after the day of ovulation, together with the day of ovulation, a total of 10 days is called the period of ovulation. After the egg is discharged from the ovary, it can survive in the fallopian tube for 1-2 days waiting to be fertilized, and the man’s sperm can maintain its ability to fertilize for 2-3 days in the woman’s reproductive tract. The days before and after the egg is discharged, sex is very easy to conceive, so the ovulation period is also known as the fertile period.
