What you can expect

By Mayo Clinic Staff

To use the cervical mucus method:

  • Record your cervical secretions for several cycles. Starting the day after your menstrual bleeding stops, observe and record your cervical secretions on a daily chart. To avoid confusing cervical secretions with semen or normal sexual lubrication, avoid sex or use a barrier method of contraception during your first cycle. Also avoid douching, which can wash out cervical secretions and make it difficult to notice changes.
  • Check your cervical secretions two times a day. Before you urinate is a good time to check. Wipe — front to back — with toilet tissue and record the color (yellow, white, clear or cloudy), consistency (thick, sticky or stretchy) and feel (dry, wet or slippery) of the secretions. Also note sensations of dryness, moistness or wetness in your vulva.
  • Plan sex carefully during fertile days. You're most fertile when your cervical secretions are abundant, clear, stretchy, wet and slippery — much like a raw egg white. If you're hoping to get pregnant, this is the time to have sex. Ovulation most likely occurs during or one day after your last day of this type of cervical secretion — known as your peak day. If you're hoping to avoid pregnancy, unprotected sex is off-limits from the day your cervical secretions begin until four days after your peak day. If you have sex before your cervical secretions begin, you may want to avoid sex the next day and night so that you don't confuse semen and arousal fluids with cervical secretions. Some health care providers also recommend avoiding unprotected sex or using a barrier method of contraception during your period because it's difficult to detect cervical secretions when they're mixed with menstrual blood.

Interpreting and charting cervical secretions can be challenging. Most women require several instructional sessions to recognize the pattern of secretions in a typical menstrual cycle. Consult your health care provider with any questions or concerns.
