Safe Period for Safe sex

Every month a woman is in safe period that means if you mate with your woman in during that time then the chances of her getting pregnant is almost nil. I say the chances is almost nil because one has to be very careful calculating the safe period. Any miss calculation will result in fertilization. So how do we find out the perfect safe period for our women?

First, one should know the duration of the menstrual cycle, i.e. first day of the last menstrual bleeding to the first day of the present menstrual bleeding. This is the duration of the menstrual cycle. This varies from person to person and it is between 26 to 31 days. Ovulation (part of a woman's reproductive cycle in which an egg is released by a mature ovarian) approximately occurs in the middle of the cycle, i.e. duration of the cycle - (minus) 14 days (this also varies).

A week before and a week after the approximate day of ovulation is considered fertile period. The days apart from this are called the safe periods, where the fertilization does not take place.
Let us take a simple example. If a women's menstrual cycle varies from 26 days to 31 days cycle.

The shortest cycle [26days] minus 18days = 8th day.
The longest cycle [31days] minus 10days = 21st day.

Thus, 8th to 21st day of each cycle counting from first day of menstrual period is considered as fertile period. Period other than this fertile period in a menstrual cycle is considered as safe period. Any intercourse during non-safe periods will surely result in pregnancy.

Hence, it is very important to calculate the safe period very accurately. However, keep in mind, intercourse in safe period just ensures that chances of pregnancy is minimum but not zero completely.
