Am I expected to enter a mucus value during my menses?

I thought the same thing, but when menses begun, the 5 Day Dry Up Rule still required that a value be entered. Otherwise it reads "Missing Mucus Values." The description indicates that values have to be entered for the entire cycle.

One of the tips I was given on the app was to start tracking mucus on day 6. I don't know what to advise if your period lasts that long.
