Would you be interested in learning natural family planning/fertility awareness? - natural family planning

I am thinking of becoming a teacher of natural family planning. I teach a method called Billings, which is very easy and helps to prevent pregnancy or a pregnancy. I teach (not just in a church, but also the general public as a community college). I wonder if women would be interested. Thank you.
