|
|
|
What is the principle behind Natural family planning method?

using the physiologic signs and symptoms.

|
1) Basal Body Temperature (BBT)
2) Cervical Mucus Method / Billing's Ovulation Method
3) Sympto-Thermal Method
4) Lactational Amenorrhea Method (LAM)
5) Cycle Calculation Method / Calendar Method / Rhythm method

|
|
What is the overall Actual Failure rate of NFP?
|
|
10-30%
|
|
back to top
|
|
What are the indications as to when we can provide NFP?
|
|
for women who do not wish to use other contraceptive methods because of health or religious or personal beliefs
for women who want to use a less effective method of family planning
|
|
back to top
|
|
What are the advantages of NFP?
|
|
widely acceptable ; no known side effects
used either to delay or to achieve pregnancy
promotes self-awareness and knowledge of the human reproductive functions.
promotes shared responsibility between couples
|
|
back to top
|
|
What are the disadvantages of NFP?
|
|
it requires commitment, cooperation, and open-communication between partners
requires daily record of signs and symptoms of fertility
"emotional stress" experienced by some couples due to the need to abstain from intercourse during certain days
|
|

|
|
What are the contraindications of NFP?
|
|
no absolute contraindications
|
|

|
|
What are the pre requisites before giving NFP?
|
|
to get client history and physical examination is not strictly necessary.
client education is very important, it requires intensive training of both partners
|

|
|
What is the principle behind BASAL BODY TEMPERATURE (BBT)?
|
during menses, a woman's BBT changes from a lower to a higher level
before ovulation (estrogen dependent), the temperature pattern is at a lower level
shortly before, during ovulation (progesterone dependent) the BBT rises
"THERMAL SHIFT"(TF)
- 0.4 - 1.0 deg Fahrenheit
- 0.05 - 0.2 deg Centigrade
Note :
- ovulation occurs 1 to 2 days before the "thermal shift" or on the day of the thermal shift
- ovulation can occur :
- 1 day after the "thermal shift"
- or rarely 3-6 days before the "thermal shift"
|
|
back to top
|
|
What are the important pointers to remember in BBT ?
|
1) BBT pattern changes from a lower to a higher level during menses.
2) by monitoring her BBT, one can determine her infertile phase.
3) safest way to avoid pregnancy is to avoid intercourse all throughout the cycle until after BBT rises and remains high for 3 days.
4) The following affects BBT monitoring :
sore throat
colds and flu
fever
toothache
vomiting
diarrhea
anxiety
sunburn
medications
travel
sleep disturbances
alcoholic beverages
|
|
back to top
|
|
How do we use BBT?
|
1) Take temperature every morning upon waking up and before any activity.
2) If not possible, take the temperature about the same time everyday after at least three hours of undisturbed rest.
3) Take the temperature (under the tongue, in the vagina, or in the rectum). The temperature should be taken in the same manner/site throughout the cycle. Rectal and vaginal temperatures are usually higher than oral temperatures.
4) Leave the thermometer in place for five minutes.
5) Read and record the temperature immediately after taking it.
6) Record it on a chart by placing a dot in the center of the box that matches the temperature printed on the left side of the chart. Connect the dots marking the temperature on a daily basis so as to see the pattern.
7) Record any unusual event such as illness, worry or any changes in the lifestyles.
|
|

|
|
What is COVER LINE ?
|
|
- it is the point of reference to determine the thermal shift due to ovulation.
This is determined by :
a) identify the first 10 temperatures of the cycle
b) disregard the temperatures for D1 - D5
c) find the highest temperature from D6 - D10
d) draw a horizontal line on the highest temp from D6 - D10. This is the coverline.
ABSOLUTE INFERTILE PHASE DAYS :
- from the rise in the temperature due to ovulation, wait for 3 consecutive days above the coverline.
- intercourse is allowed from the 4th day of the thermal shift until the end of the cycle. This is infertile phase of the cycle.
|
|
back to top
|
|
What is the principle behind the CERVICAL MUCUS METHOD ?
|
|
- uses the changes in the cervical mucus consistency as to predict ovulation and to determine when it has occurred.
1) After menses ends
most women - no mucus
vaginal feels dry
these are called dry days
2) After the dry days
mucus - sticky, pasty or crumbly
color - white or yellow
vagina - still dry, little sticky
these means that ovulation is coming, this is considered a fertile time
3) As ovulation gets nearer
mucus - welt, increases in amount
color - clearer
4) At the time of ovulation
mucus - very wet, stretchy and slippery (raw egg white)
vagina - feels very wet
this will last for several days
the last day of the wet and slippery mucus is called the peak day
5) After ovulation
mucus - very sticky, and pasty, decreases in amount
|
|
back to top
|
|
INFERTILE PERIOD
|
|
4th day after the peak day and continues until menstruation begins
|
|
back to top
|
|
How do we use CERVICAL MUCUS METHOD?
|
|
- requires the woman to observe what she feels and sees at her vulva and record
1) Begin checking the mucus - WHEN ?
the menses ends or becomes lighter
there is no prior sexual intercourse, and
a woman is not sexually stimulated
2) Check the sensation of wetness and dryness while standing
3) Inspect underwear regularly for the presence of mucus
4) Wipe across the opening of the vagina with a piece of clean tissue paper, clean cloth or clean finger.
5) Using the middle/index finger and the thumb, test the consistency, the slipperiness, the stretchiness and the color of the mucus.
|
|

|
|
What is the principle behind SYMPTO-THERMAL METHOD (STM)
|
|
it is a combination of Basal body temperature (BBT) and Cervical mucus method as well as other signs that help identify her fertile time.
|
|
back to top
|
|
What are the "OVULATORY SIGNS" ?
|
|
dull ache or sharp pain in the area of the ovary lasting from a few minutes to a day or two
fluid retention (swelling of the hands and feet)
increase or decrease in sexual desire
slight bleeding for one or two days may occur (noted during ovulation)
AFTER OVULATION (BEFORE MENSES)
oily skin and hair, pimples or increase in acne
uterine cramps
low back pains
craving for sweets and/or salty foods
breast tenderness
increase or decrease in sexual feelings
|
|
back to top
|
|
How do we use STM?
|
|
The acceptor of this method is required to observe her BBT, cervical mucus and other and to record them in a chart.
|
|
back to top
|
|
What are the rules to observe in STM?
|
1) Intercourse can occur during the first 5 days of the menstrual cycle if the peak day and thermal shift rules were applied
2) Menstruation days are relatively
infertile days - average or long cycles
fertile days - short cycles
3) After menses, intercourse can occur on the evening of every other dry day during the infertile days before ovulation
4) The first day a woman observes any type of mucus or when she begins to feel wet sensation, it is the beginning of the fertile phase.
5) Couples abstain from intercourse until the peak day rule and thermal shift rules have been applied whichever comes later.

What is the principle behind the LACTATIONAL AMENORRHEA METHOD (LAM)
|
it involves post-partum women
effectiveness of breastfeeding as a contraceptive is brought about by the increased sucking frequency
RETURN OF OVULATION :
