How many days a month is pregnancy possible?

Pregnancy is generally possible for about 6 days in a month, typically around the time of ovulation. Ovulation usually occurs around 14 days before the start of a woman's next menstrual period. The fertile window includes the day of ovulation and the five days leading up to it, as sperm can survive in the female reproductive tract for several days. Therefore, the likelihood of conception is highest during this period.
