The table is a calculation that is made based on the days of the menstrual cycle to know when the woman is fertile period and, therefore, it can contribute to the woman knowing when she can not have intercourse, because she is in danger of becoming pregnant.
However, as a contraceptive method it is not very effective and there may be flaws, a woman should not rely only on the table, but associate another contraceptive method, such as a condom, for example to increase protection and avoid an unwanted pregnancy.
What days can not be related
Anyone who is not wanting to become pregnant can not have intercourse during their fertile period, which is between the 11th and 17th day, from the first day of the menstrual cycle, in a 28-day cycle. As the woman may have a more irregular cycle, these days may vary from one month to the next, and that is why the table should not be used as an exclusive method to avoid pregnancy.
To calculate the days of the fertile period in case of a regular menstrual cycle, what you need to know:
- What is the interval between 4 menstrual cycles, to count how many days your menstruation takes to go down;
- If you find that the interval is not always the same, you should find an average of days;
- After that, divide this number by 2 to find exactly the middle of the cycle;
- The middle day of the cycle is the most fertile day of the month;
- And the fertile time is the 3 days before and 3 days after that day.
