Not at all, this is a method that has been around since the 1950s and is proven by research.
FAM as it exists today, was developed around the same time as the pill was released to the market. Actually, over 150 years ago, scientists began to notice the changing cervical secretions, the cervix and the temperature during the female cycle.
Only in the 50’s was the Billing’s method formed. This method is based on tracking just the cervical secretions and was taught strictly by the Catholic Church.
In the 80’s, the Fertility Awareness Method was created, combining the tracking of three fertility signs, allowing much higher efficacy, compared to other natural methods that exist today.
During the 90’s, FAM arrived to Israel from United States via Michal Schonbron and Katia Sider. Michal teaches the method and trains teachers til this day and I had the honor of being one of her students.
