I think it would be super helpful to be able to add notes and color coordinate them for the menstrual / fertility tracker. Ex: Dates where I change birth control methods or getting my second vaccine dose.
Aside from mood I think appetite and bowel movement icons would be great too as they often fluctuate along with my cycle.
A lot of variables effect my cycle and having the ability to track that would allow for people to have more insight and make connections.
