Fertility awareness aka Natural Family
Planning is a collection of methods using
your body’s natural and normal functioning
to determine the days of the month you are
most likely to get pregnant.
Natural Family Planning is a method of birth
control that does not use any drugs or
devices. It combines the calendar/rhythm
method, the basal body temperature
method, and the cervical mucus method.
Used both as a means of preventing
pregnancy as well as targeting the most
fertile time for getting pregnant.
The calendar; basal body temperature;
and cervical mucus methods are
combined to give you the awareness of
when your body is most fertile. As you
become familiar with your body’s
ovulation and fertile periods, it provides
you the opportunity to abstain from
sexual intercourse or use a barrier
method during that time.
First of all become familiar with your
menstrual cycle and to begin charting
your fertility pattern.
The average menstrual cycle is between
28 to 32 days, however there are two
parts related to your cycle: before
ovulation and after ovulation.
Day 1: The first day of your menstrual flow is
the beginning of your cycle.
Day 7: By day seven your egg is preparing
to be fertilized by sperm.
Days 11-21: (based on 28-day cycle)
Hormones in your body cause the egg to
be released from the ovary around this
time. This process is known as ovulation. The
egg travels through the fallopian tube
towards the uterus. If sperm penetrates the
egg, the fertilized egg will attach to the
lining of the uterus and begin to grow. If
fertilization does not happen the egg
Day 28: Hormone levels drop around this
day causing the lining of the uterus to be
shed making up your menstrual flow.
Step 1: Plan on tracking your menstrual cycle for 8 to 12
Step 2: Day 1 will be the first day you start menstruation.
Step 3: Pick the longest and shortest of the cycles from your
Step 4: The first day of your fertility period is determined by
subtracting 18 days from the length of your shortest cycle. If
26 days was your shortest menstrual cycle, take 26 and
subtract 18 to come up with the number 8. This means that
the first day of your fertility window starts on the 8th day of
Step 5: The last fertile day is determined by subtracting 11
from the length of your longest cycle. If 32 days was your
longest menstrual cycle, take 32 and subtract 11 to reach the
number 21. This means that the last day of your fertility period
ends on the 21st day of your cycle.
Step 1: Take your temperature orally each
morning before you become active.
Step 2: Use a basal thermometer which
recognizes small changes in your
temperature. Your body temperature will
only rise between 0.4and 1 degree
Fahrenheit when you ovulate. Buy a Basal
Step 3: Record you temperature every day
on your fertility tracking calendar.
Step 1: Collect the mucus from the vaginal
opening with your fingers by wiping them
from front to back.
Step 2: Record it daily on your fertility
calendar by making note of the colour
(yellow, white, clear or cloudy), the
consistency (thick, sticky, or stretchy) and
the feel (dry, wet, sticky, slippery, stretchy).
Step 3: Ovulation is recorded on the day
that your mucus is clearest, slippery and
When fertility awareness is used correctly
and consistently, it may reach effective
rates around 90%.
Typical use, which refers to the average
use, shows a failure rate of approx. 25%.
If you are committed to tracking and
recording your fertility information, you
can achieve much higher success rates.

associated with Natural Family Planning.
Yes. Fertility awareness does not have
any effects on the male or female
reproductive functioning. Pregnancy is
possible immediately following the
practice of fertility awareness.
