This chart is an example of an anovulatory cycle of a woman trying to conceive. There is no temperature rise and her cervical mucus never goes beyond the sticky and creamy state so it is apparent she did not ovulate. Without ovulation, this woman did not conceive this cycle.
What is going on in this chart?
1) No sustained rise in temperature means that ovulation has not occurred.
2) Cervical mucus does not reach peak fertility, remains in a sticky, creamy pattern until the end of the cycle.
