It would seem that some readers would benefit from the expertise of those who have looked at and provided answers to the difficult cases requiring Natural Birth Regulation.
So these include:
Creighton Model
Billings Ovulation Method
The Marquette University Institute for Natural Family Planning
Family of the Americas Foundation

The efficacy of NBR may be gauged from the great work of Mrs Mercedes Wilson.
Wilson’s Family of the Americas Foundation now teaches NBR in more than 100 countries, including China. “God would not be so cruel that unless you can read you can’t follow natural family planning,” she insists. “Why make it so complicated?” Wilson’s bold decision to dispense with the thermometer and rely solely on observations of mucus was followed by the Billings in Australia several years later.
NBR families, whether Couple to Couple or Billings followers, report an astonishingly low divorce rate — one informal study puts it at 1.3 percent, as compared with about 50 percent in society at large. Even accounting for the high level of dedication of the NBR group studied, experts estimate that the divorce rate for NBR couples does not go above 4 percent. Wilson’s Family of the Americas has a study that shows a 2 percent divorce rate. Advocates say that NBR promotes communication between husband and wife because both must be involved. Husbands are encouraged to help with the charting.
Wilson claims an effectiveness rate of 99 percent among “the poorest of the poor” in Guatemala. “There’s no excuse anymore to pretend that only those with strong religious convictions can follow natural family planning,” [NBR] she writes.
Unlike the rhythm method, the Billings method does not depend on a stable menstrual cycle. Numerous independent trials have confirmed the 99 percent success rate of the Billings Method, including a recent study following thousands of women for more than a year. If any further proof is needed, the method has been regularly used up to date by over 2,686,400 fertile couples in China for avoiding pregnancy with an overall success rate of approximately 99 percent.
