"The hormonal balance that regulates ovulation acts throughout our body, including the brain, thus indicating that ovulation can be understood as a sign of adequate health status that women can easily recognize."

FEMM-Certified Physician

"Fertility awareness models are the key to preventative medicine because they get to the heart of the problem. Most women stop using contraception because of side effects. What a great alternative to have a model that is free of side effects and helpful in diagnosing health problems."

Dr. Pilar Vigil


"The first sign of an underlying health problem a woman may experience is ovulatory dysfunction, followed by irregular cycles or amenorrhea. Indeed, when pregnancy, lactation, or menopause are not the causes, persistent irregularities in the ovulatory cycle can be associated with lifestyle, stress, drugs, and endocrine, gynecological, autoimmune, nutritional, genetic, and iatrogenic disorders."
