When is the fertile period?: Before or after menstruation?


Women who have a regular menstrual cycle that lasts 28 days, the fertile period begins on the 11th day from the first day when menstruation occurred and it lasts up to the 17th days, and these are the best days to become pregnant.


However, women who have irregular menstruation periods, the calculation of the fertile period should be done while taking into account the last 12 months of the cycle.

Fertile period in regular menstruation


For women who have a regular menstruation cycle, ovulation occurs around the 14th day of the normal 28-day cycle. The fertile period will therefore take place 3 days before and 3 days after that date.

For example, if your menses come on the date 10th, the fertile period after menstruation will be between the 20th and 26th. The most fertile day will be on the 23rd, as this will be the central date of the fertile period. In some cases can use a fertile period calculator to be able to know the fertile period.

Fertile period in irregular menstruation

The fertile period for a woman with irregular menstrual cycle is difficult to determine. The calculations are usually not safe for those who are either trying to get pregnant or those who do not want to become pregnant. This is because, menstruation does not always appear on the same days, therefore the accounts may wrong.

Irregular periods

However, it is still possible to get an idea of when the fertile period is in the case for an irregular cycle. One should take note of their menstrual cycle for a year, the duration of the cycle 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 28 days, then it will be, 22 – 18= 4 and 28 – 11 = 17.Therefore the fertile period will be between the 4th and 17th days of the full menstrual cycle.

A more rigorous way to determine the fertile period for a woman with irregular period and who may want to become pregnant is to take the ovulation test. This test is found in the pharmacy and it is advisable to beware of the signs experienced during the fertile period. These include, egg-white like discharge and increased sexual desire.
