most women temperature usually rises slightly
with ovulation and remains up during the second
part until just before her next period Recording
each days temperature helps to indicate when ovulation
has occurred .
temperature method requires charting your basal
body temperature (BBT), the temperature your body
registers when you’re completely at rest. BBT
varies slightly from person to person. For most
women, 96 to 98 degrees taken orally are considered
normal before ovulation and 97 to 99 after. The
changes are small fractions – from 1/10 to ˝ degree.
So it’s best to get a special, large –scale, easy-to-read
thermometer that registers only from 96 to 100
degrees. A rectal reading is more reliable. But
whichever you choose, take your temperature the
same way every day.
morning take your temperature, as soon as you
wake up – before getting out of bed, talking,
eating, drinking, having sex, or smoking. Either
insert the thermometer in your rectum or place
it in your mouth for a full five minutes. Read
the temperature to within 1/10 of a degree and
record the reading.
Your Temperature Pattern
reading must be recorded If you wish to have one
As each day’s temperature is plotted
on the graph, you will learn to recognize your
own pattern. Your temperature rise may be sudden,
gradual, or in steps. The pattern may vary from
cycle to cycle .
You must also realize that physical or emotional upsets or even lack
of sleep can influence your BBT. In addition, illness, emotional distress, jet lag,
disturbed sleep, smoking, drinking an unaccustomed amount of alcohol the night before, and
using an electric blanket may affect your body temperature.
In the beginning you should get
help in reading your BBT chart from a physician, nurse ,or family
the temperature rise has lasted for at least three
days, you can assume that your safe days have
begun. They will last until the temperature drop
that usually comes just before the onset of your
next menstrual period. For complete protection,
consider unsafe all the days between the start
of your period and the start of the fourth day
of the next temperature rises
When you become confident about
using your BBT to determine your safe days, you
may not need to take your temperature between
the start of the infertile time and the beginning
of your next menstrual period.
