The Calculation of the Fertile Period after Menstruation

The fertile period after menstruation can be easily calculated.  You can even do it yourself to support the process of pregnancy. Menstruation is the release, through the vagina, of the uterine lining which contains many blood vessels (endometrium). These layers are formed in preparation when the egg is fertilized by a sperm cell. If the egg is not fertilized, then the tissue is lost as menstrual blood.

A regular menstrual cycle takes about 28-30 days, with menstrual bleeding lasting between 3-7 days. Normal menstrual cycles make it easy to calculate the fertile period of a woman.

Example Calculations of the Fertile Period After Menstruation

Women with Regular Menstrual Cycles

Use this method when the menstrual cycle is normal and regular, i.e. between 28 - 30 days. The first day of menstrual bleeding is counted as day 1. The fertile period is from day 12 until day 16 of the menstrual cycle. For example, if menstruation begins on January 9th, that date marked as day 1. The fertile period is from the 12th Day (January 20th ) until the 16th day (January 24th ).

Women with Irregular Menstrual Cycles

Irregular menstrual cycles are characterized by menstruation that comes too soon or too late, and therefore cannot be predicted. This will affect the level of fertility and the calculation of the fertile period.

Instead, record the number of days between the start of menstrual bleeding from one month to the next for 6 months. The first day of the fertile phase is the last day of the shortest menstrual cycle minus 18. The end of the fertile period is the last day of the longest cycle minus 11. The menstrual cycle Influenced also by women's health conditions.

Summary:

• The fertile period in a regular menstrual cycle is from the 12th day until the 16th day of the cycle,
• The calculation of the fertile period is easier for women who have regular menstrual cycles.
