Understanding your body is very important, especially when it comes to your menstrual cycle. One useful tool for women is the Safe Period Chart. This chart helps women to know when they are least likely to get pregnant. It is a natural method of family planning.
What is a Safe Period?
The safe period is the time in a woman’s menstrual cycle when she has a lower chance of getting pregnant if she has sex. This time is based on the fact that a woman can only get pregnant on certain days of her cycle.
The days that are not fertile are called the safe days.
How Does the Menstrual Cycle Work?
A normal menstrual cycle is about 28 days, but it can range from 21 to 35 days. Here's how it usually works:
- Day 1 to 5: Menstrual period – bleeding happens.
- Day 6 to 9: Post-period – the uterus starts preparing again.
- Day 10 to 17: Fertile window – ovulation happens (egg is released).
- Day 18 to 28: Safe days – lower chance of pregnancy.
What is Ovulation?
Ovulation is when an egg is released from the ovary. It usually happens around the 14th day of a 28-day cycle. Sperm can live for up to 5 days, and the egg survives for 24 hours.
How to Use the Safe Period Chart
Step 1: Track Your Period
Write down the first day of your period for at least 6 months. Count how many days are in each cycle.
Step 2: Find Shortest and Longest Cycle
Example: Shortest = 26 days, Longest = 30 days
Step 3: Calculate Fertile Days
- 26 − 18 = Day 8
- 30 − 11 = Day 19
Your fertile window is from Day 8 to Day 19.
Step 4: Mark Safe Days
Days 1–7 and Days 20–28 are generally safe.
