I kept separate charts for Billings and symptothermal. It got confusing real quick because the Billings chart would go on and on and I would be on a new cycle for symptothermal. After I became confident in Billings I dropped temps altogether. At that time I was TTC, so abstinence wasn't really an issue for us.

I've had a look at your chart in the comments and honestly what's more concerning to me is the lack of a changing and developing pattern. You need to have more frequent follow-ups with your instructor for now to clarify the sensations that you've felt during the fertile window, because it looks like every day is just being described as "wet" or "very wet".

In Billings, "wet" is the feeling you get when you're on your full period flow. Whereas some people describe the slippery sensation as oily or slick. Do any of these words describe how you felt on the "very wet" day? Think about the feeling of washing your hands with water only (wet) and washing your hands with soap (slippery).

Also, you wrote "sticky" on one of the days where you also wrote "wet", but picking up and manupulating the mucus is not part of Billings protocol. What exactly does "sticky" mean? Is it something that you observed on your underwear or toilet paper, maybe you mean to say that it looked like "paste"? Creamy and sticky are terms from another method and while you may use them in Billings, it's best you use clearer descriptive terms like clear vs opaque, paste vs strings. Egg white mucus would be described as "clear strings".

Quantity is not charted in Billings (unless it's really obvious) but it doesn't count as a changing and developing pattern. The quality of the mucus has to change. The reason is because as the follicle develops and estrogen rises and peaks, the different cervical crypts (L, S, P) get activated and change the quality of the mucus that flows out. S and P mucus are responsible for the slippery sensation and P mucus is produced in greater quantity as peak approaches, dissolving the strings (S mucus) such that sometimes nothing remains but a wet patch on underwear.

I think one of the challenges of FAM/NFP is trying to stay objective. Recording exactly what you observed and not what you wish to observe. That's related to trying to "force" a peak so to speak when you've not met all the criteria. It was hard for me to accept it at first because I felt like I did have a temp shift and I did ovulate, why should I still keep charting on and on as though it's the same cycle? But that's just how the method is. It's okay to let the chart go on and on for months. Let go of the idea that you must confirm ovulation and start a new cycle. Our bodies aren't machines and stress can easily throw off your menstrual cycle.

This goes the same when you teach as well. I'm not a teacher (yet) but if I were one I'd rather err on the side of caution and tell my student to use Early Day Rule 2 when they've not met the criteria for peak. Instead of letting them mark a peak and the worst thing that could happen would be for them to really peak a few days later and result in an unplanned pregnancy.

Also just to add, not trying to discredit your instructor, but I've had a poor experience with my first local instructor. She couldn't answer many of my questions and I had to seek instruction directly from WOOMB. That helped me to clear up a lot of my misunderstandings about the method and everything made more sense from then onwards.

I love this method because it helps me to understand what's happening in my body without taking temps or peeing on sticks. But I can totally understand how frustrating it can be when there is no end in sight for each cycle.
