For some women, they will determine their cycle because it's regular or they might count it well.
For others, the irregularity makes it difficult to work out the cycle and to notice their safe periods, or they might not just count it.
What happens during the cycle is this; Using a regular 28 days cycle, the lady in her reproductive years sheds egg (ovum) from the ovary at every 14days following the menses.
Not a requirement that it'll be 14days because it can shed on the 12th day or 13th day and also the egg are often shed on the 15th day or 16th day of the cycle which is named ovulation.
The egg is carried into the womb through a tube called the Fallopian tube. within the process of passing along the tube, it could get fertilized by the male sperm ( that's, if intercourse had occurred ).
This is often why the time is claimed to be an unsafe period. But if no fertilization occurs, the womb, which had already prepared itself to receive the embryo, will hand over and shed its walls to release bloody discharge referred to as Menses.
If fertilization had taken place , then the womb remains intact and there'll be no discharge or if in the least a really small discharge.
This is the rationale why pregnancy is suspected when menses fail to occur and you've got to ascertain a doctor.
