Although it is a little more difficult to know exactly when the fertile period is for women who have irregular periods, it is possible to get an idea of what the most fertile days of the month might be, taking into account the last 3 menstrual cycles.
For this, it is important that the woman writes down the day of each cycle on which menstruation occurred, in order to know the days of each cycle, in order to be able to calculate the most fertile days.
how to calculate
To calculate the fertile period, the woman must take into account the last 3 cycles and note the days on which the first day of menstruation occurred, determine the interval between those days and calculate the average between them.
For example, if the time interval between 3 periods was 33 days, 37 days and 35 days, this gives an average of 35 days, which will be the average duration of the menstrual cycle (to do this, just add the number of days of 3 cycles and divide by 3).
After that, 35 should subtract 14 days, which gives 21, which means that the 21st day is when ovulation occurs. In this case, between one period and another, the most fertile days will be 3 days before and 3 days after ovulation, that is, between the 18th and the 24th after the first day of menstruation.
how to protect yourself
For those who have an irregular cycle, the best strategy to avoid unwanted pregnancy is to take the contraceptive pill that will regulate the flow days, remembering to still use a condom in all relationships to also protect yourself from sexually transmitted infections.
Those trying to get pregnant can also try buying ovulation tests at the pharmacy to be sure of the most fertile days and to invest in intimate contact during those days. Another possibility is to have sex at least every 3 days throughout the month, especially on days when you can identify the signs of the fertile period, such as temperature change, the presence of mucus in the vagina and increased libido, for example.
