Fertile period in irregular menstruation
The fertile period in the irregular cycle is difficult to determine and its calculations are not safe for those who are trying to conceive or for those who do not want to get pregnant, as menstruation does not always appear on the same days, the calculations can be wrong.
However, it is possible to get an idea of the fertile period in case of an irregular cycle, by writing down the duration of each menstrual cycle for a year and then subtracting 18 days from the shortest cycle and 11 days from the longest cycle.
For example: If the shortest cycle was 22 days and the longest cycle was 28 days, then: 22 – 18=4 and 28 – 11=17, that is, the fertile period will be between the 4th and the 17th day of the cycle.
A more accurate way of determining the fertile period for women who wish to become pregnant is to take the ovulation test, which can be found at a pharmacy, and pay attention to the signs of a fertile period, such as discharge similar to egg white egg and increased sexual desire, for example.
