When a woman has very long cycles which may last weeks or even months, the woman knows that she is not fertile, either because of dryness or because of the constant presence of an unchanging vaginal discharge which remains the same day after day after day. This discharge is quite different from the mucus seen when a woman is ovulating normally.
The rule that must be followed is: Observe two consecutive weeks of this unchanging discharge before it can be considered infertile. The couple can then apply the Early Day Rules: Sexual relations are open to the couple only in the evenings of every other day. However, when there is a change in her basic infertile pattern , (A change in sensation; the appearance of mucus; a wet or slippery feeling; a change in the amount of discharge or in its color, consistency or feeling) a fertile phase may have begun.
Once the fertile phase begins, delay intercourse until the mucus becomes elastic, wet and slippery.
Note Well:
Some women do not see the clear and elastic characteristics of the mucus, but experience it only as a wet, slippery feeling. This is a fertile sign and the couple should use these days to achieve pregnancy.
A few women experience the fertile characteristics of the mucus for only a few hours. This observation is often made in the morning. In this circumstance the couple should time intercourse to take place that morning or when the fertile characteristics of the mucus are present at any other time of the day.
