The best day to conceive usually refers to the day when a woman ovulates and the 24-48 hours before and after it, because during this period, the egg activity is higher and the fertilization ability is stronger. If a woman\’s menstrual cycle is regular and her ovulation date is relatively accurate, she has a greater chance of getting pregnant. Sperm can survive in a woman\’s body for 2-5 days, so the few days before and after ovulation are also periods when the probability of pregnancy is higher. In addition, some research shows that the human body may be in a better state between 9 pm and 10 pm, and having sex during this time may help increase the chance of pregnancy
