If the menstrual cycle of a woman is regular, i.e. of 28 days, then day 1 to day 7 and from day 21st are the safe days for a woman. However, this calculation is not same for every woman as it depends on the length of the menstrual cycle. Therefore, if your menstrual cycle is longer than the 28 days, then this calculation may not be reliable to you.
To understand and calculate the safe periods or the safe days, you need to understand the stages of menstrual cycle. This menstrual cycle undergoes with three stages – Pre-ovulatory, Ovulation, and Post-ovulatory.
First stage: During Pre-ovulatory stage, body releases hormones that stimulates the eggs in the ovaries to grow. It usually occurs in between day 2 to day 14 of the menstrual cycle. This released hormone will make the uterus lining thick so that the eggs can get fertilised.
Second stage: At Ovulation stage, egg is ready to get fertilised. It occurs on the day 14 onwards. These days are the most fertile days of a woman. The probability of getting conceive is likely to be higher.
And lastly that is third stage: During post-ovulatory stage, the pregnancy either starts or uterus prepares for other menstrual cycle.
