• progesterone released by the ovary after ovulation causes the basal body temperature<br />
to rise<br />
• there are changes in the cervical mucus that provides information about the phase in<br />
the cycle<br />
− cervical mucus is scant, slippery and may be milky coloured prior to ovulation<br />
− mucus is abundant and becomes sticky and stretchy during ovulation when<br />
woman is fertile<br />
− mucus becomes scant and rubbery after ovulation when woman is no longer<br />
fertile during that cycle<br />
• women are more likely to become pregnant when ovulating<br />
The fertile period of the menstrual cycle, may be calculated 4 ways:<br />
1. Basal Body Temperature (BBT) method: daily temperature readings detect<br />
ovulation.<br />
2. Cervical Mucus (Billings) method: changes in cervical mucus show signs of<br />
ovulation.<br />
3. Sympto-thermo method: a combination of the temperature and cervical mucus<br />
methods.<br />
4. Calendar method: the length of past menstrual cycles predicts the fertile period<br />
Warning: This method depends on a consistency of cycle length. It is common<br />
for young womenÕs cycles to vary from month to month. For these young women,<br />
this method should not be recommended.<br />
How the Methods Work<br />
Basal Body Temperature<br />
Take your temperature with a special thermometer (available in drug stores) each<br />
morning immediately upon waking. Take it for 4 minutes the same way each day. Record<br />
your temperature on a graph and note the days of menstruation, sexual activity and any<br />
factors influencing your temperature. Draw a line on the graph one tenth of a degree<br />
higher than the highest temperature recorded earlier in the cycle. When the temperature<br />
remains above this line for three days in a row, the fertile period is over.<br />
* Effectiveness: perfect use 2%, typical use 20%<br />
Cervical Mucus<br />
Use your fingers to examine the cervical mucus present at the vaginal opening every day.<br />
Each day you note sensation at the vulva (dry, moist or wet), colour of the secretions<br />
(yellow, white or clear), and consistency (slippery, sticky or rubbery).<br />
