The fertile period lasts around 6 days and generally occurs 14 days after the first day of menstruation, in women who have a menstrual cycle of 28 days, which is considered regular.
This period is considered fertile because during this period there is an increase in libido and greater production of vaginal secretion, which favors the movement of sperm through the uterine tubes, for example, which can survive for around 5 days, in addition to corresponding to the period in which it occurs. ovulation.
Therefore, this fertile period is calculated taking into account that there is a greater probability of getting pregnant 5 days before ovulation and 1 day after ovulation, as the egg’s lifespan is approximately 1 day. For example, if a woman has intimate contact on day 5, and if that is the first day of her fertile period, her egg is probably not yet mature. However, the sperm can remain inside the vagina until day 8, which is when ovulation can occur, and it is still possible to be fertilized by the sperm that remain alive, which can result in the conception of a baby.
How to calculate the fertile period?
Ovulation occurs 14 days before menstruation, and generally, in women with a 28-day cycle, it happens halfway through. However, many women have shorter or longer cycles and, in these cases, it can be more difficult to know when ovulation occurs.
To calculate the fertile period, simply subtract 14 days from the number of days in the cycle. For example, in a woman who has a 32-day cycle, if 14 days are subtracted, it gives 18, which means that ovulation occurs on the 18th day counting from the first day of menstruation. The fertile period is then the period of time that comprises the 3 days before and 3 days after ovulation, that is, between day 15 and day 21.
Therefore, a woman who is trying to get pregnant should have as much sexual intercourse as possible during this period.
