Although there is no exact figure for the chances of getting pregnant during the fertile period, the relative time period is high, and it varies from person to person. The fertile period is the period of ovulation. For women who have regular menstrual periods, the week before and after the 14th day before the next menstrual period may be the period of ovulation; for women who have irregular menstrual periods, it is difficult to predict ovulation through the speculation of the fertile period. Ovulation occurs when the egg is released and can therefore form a fertilized egg after fertilization. Fertilization usually occurs within 24 hours after the egg is released. The chances of pregnancy are higher if you have intercourse during this period, but how big varies from person to person. If you have a medical condition that causes infertility, your chances of conceiving even during the fertile period are low. If you are planning to conceive, it is recommended to complete the preconception examination, relax, and if necessary, monitor ovulation to guide coitus.
