It’s a common myth that ovulation happens on day 14 of the menstrual cycle, or 14 days before the next period. In reality each person is different, and ovulation could be anywhere from 9 to 16 days prior to the next period!
In fact, research has shown that miscalculating the fertile phase of the cycle is a big reason a lot of people are supposedly “infertile.” In reality they just got the days wrong!
One of the most common myths about the Fertility Awareness Method (FAM) is that it doesn’t work to prevent pregnancy. And when women are learning how to use it they always want to know how effective it is. At perfect use, it’s 99.6% effective, as good as hormonal contraception! (something a lot of people don’t know).
So how do we know this? Science! Keep reading to see the research that backs this up.
