Cervical mucus method


In this method, there is reliance on the natural cyclicity which the cervix undergoes in the production of mucus. It produces two main mucus types. To this two, we add two more signs- dry (when the cervix is not producing any mucus) and menses, which is blood from the uterus. There are therefore four signs to use in the cervical mucus method.

  • Dry

  • Menses

  • Pap- cloudy non stretching mucus

  • Eggwhite- clear and transparent stretching mucus

These are used to make a chart following a special method.


Use a clean cloth or tissue to wipe the lips of the vagina at a specific time during the day when it is convenient for you. Some use the morning just after waking up from sleep. Others use other times to avoid false positive results. For example, you must not confuse mucus from vaginal secretion as a result of sexual arousal with that of cervical mucus which flow freely when available, without any stimulus. Also you must treat any form of vaginitis, which may cause discharge as these can give wrong results. Finally, you must test your cervical mucus only when semen which was discharged  as a result of previous sexual intercourse has had the opportunity to clear completely. For example, if you had intercourse the night before, by midday (if we walking about) it should have cleared from the vagina.

Examine the tissue or cloth to see if there is any mucus on it. If none, then you are at the dry period. If there is mucus, see if it is clear or transparent or cloudy. Then touch to see if it stretches and then classify accordingly. Any form of bleeding must be classified as 1 even if it is during the midcycle. Then chart and join the points together later. You will see a pattern similar to this one below, if you have a normal cycle. The cervical mucus method follows closely reproductive cycle in the female and is the basis for he cervical cycle itself.

There are very man variations in the normal pattern, including examples of how the chart can be used to identified abnormalities leading to infertility as follows

  • Persistent dry (2)
  • Persistent pap (3)
  • Persistent menses (1) or hypermenorrhea
  • Persistent eggwhite (4) caused by cervical cysts
  • Double infertile sign (persistent 2 and 3 combined)
