Group Recommended Billings Instructors

Hello! My name is Yareline and I’m a certified Billings Ovulation Method instructor. I discovered fertility awareness/natural family planning methods after coming off hormonal contraception and searching for an effective alternative. In order to gain confidence in my cycle charting, I worked with an instructor and was amazed at what I learned. If only I had learned about this sooner! I ended up learning two methods.

I enjoy teaching others the valuable, life-changing, and empowering skill of being in tune with your body + knowing how to manage your fertility without drugs/devices/barriers. I offer live, online group classes as well as individual instruction. I also speak Spanish.

The Billings Ovulation Method is a cervical mucus/vulval sensation only method that can be used in all life stages of reproductive life:
•regular cycles
•irregular cycles
•post hormonal contraception

I look forward to working with you!

I am a certified NFPTA instructor and in practicum in the Billings Ovulation Method. I teach live online fertility awareness based method classes in the Billings Ovulation Method (mucus/sensation only) and in the double check sympto-thermal method (temperature & cervical mucus/sensation). I’ve practiced charting myself since January 2017, and I currently work full time as a librarian. I have a special interest in helping folks chart to avoid, and my classes are secular. Your partner is always welcome to attend my class with you at no additional charge. Reach out to me to see if I can help you in your charting journey! Find me at and on Instagram @chartyourfertility.
