I tell everyone I know about this method especially my younger friends who are just getting married. It's so much better for your body than taking the birth control pill and there is something spiritual connected to the method. I saw a reproductive endocrinologist who ran several blood and dye tests and performed a laparoscopy on me. She reported her findings and told me I had small ovaries for my age, diseased fallopian tubes, and my only option was IVF using donor eggs! I was only 32 years old!! I am so glad I did NOT take her advice and instead found this method since …all I did was chart and had some shots of Progesterone once the pregnancy was confirmed. Science cannot explain everything and sometimes you have to go on faith. I am so glad I did.
