The Marquette Method of Natural family planning integrates multiple biological indicators of fertility, when appropriate, to optimize detection of the fertile window. What sets the Marquette Method apart from most other methods is its incorporation of hormone monitoring and simplifying sometimes ambiguous signs of fertility. Monitors such as the Clearblue monitor, or Mira monitor, can be utilized in conjunction with the Marquette algorithm to detect patterns of ovulation, giving greater clarify to the fertile or infertile windows. Tracking other biological indicators such as cervical mucus or basal body temperature is optional in the Marquette method, but can provide further clarification depending on the individual circumstance. Many Marquette Method users say that using a fertility monitor helps take much of the guesswork out of NFP. All of the instructors who teach the Marquette Method of NFP are healthcare professionals and will work with each client individually to custom fit the method in a way that works best with their needs. This method is especially helpful for women who are postpartum, but is also beneficial to women who are trying to avoid or achieve pregnancy in either irregular or regular cycles as well. Women who have diminished cervical mucus may benefit from the urinary hormone monitoring to provide further clarity on the timing of ovulation.
