How To Prepare
Before you use fertility awareness as
a method of birth control, record three or four of your menstrual cycles to find your
pattern of ovulation. If you are trying to not become pregnant during this
time, use a method of birth control that does not affect ovulation (such as a
condom, diaphragm, or the copper
intrauterine device [IUD]) or do not have sex.
Basal body temperature is checked using a special oral thermometer marked
in fractions of a degree so you can see even small changes in temperature
better than with an ordinary thermometer. Easy-to-read digital thermometers can
be found in most pharmacies or at family planning clinics. Do not use a digital
ear thermometer for this method.
