The fertile period lasts about 6 days and usually happens 14 days after the first day of menstruation in women who have a 28-day menstrual cycle, 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 displacement of sperm through the fallopian tubes, for example, which manage to survive for about 5 days, in addition to corresponding to the period in which it occurs. ovulation.
Thus, this fertile period is calculated taking into account that you are more likely to get pregnant 5 days before ovulation and 1 day after ovulation, as the egg lifetime 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, sperm can remain inside the vagina until day 8, which is when ovulation can occur, and it is still possible to be fertilized by sperm that have remained alive, which can result in the conception of a baby.
How to calculate the fertile period?
Ovulation occurs 14 days before menstruation, and usually, in women with a 28-day cycle, it happens midway through. However, many women have shorter or longer cycles, and in these cases it can be more difficult to know when ovulation is taking place.
To calculate the fertile period, just subtract 14 days from the number of days in the cycle. For example, in a woman who has a 32-day cycle, subtracting 14 days gives 18, which means that ovulation occurs on the 18th day counting from the first day that her period started. The fertile period is then the period of time comprising the 3 days before and 3 days after ovulation, that is, between the 15th and the 21st.
Therefore, a woman trying to get pregnant should have as much sex as possible during this period.
