The chances of pregnancy vary depending on the time of the month. For example, within three days after menstruation, when the lining is thin and not in ovulation, the chances of pregnancy may be around 10%. If you have intercourse during ovulation, the chances of pregnancy may be higher. Ovulation is usually around 14 days before menstruation, and if your menstrual cycle is normal, the chances of pregnancy may be increased by about 60%. If you enter the luteal phase after ovulation, the chances of pregnancy at this time are also smaller, and the chances of conception may be around 20%. Therefore, the chances of pregnancy depend on each person’s menstrual cycle. The length of the menstrual cycle determines the number of days to conceive, or the chance of pregnancy. Also mood stress can determine the chance of getting pregnant, or conceiving.
