Female led relationships discussion

Over the past four months, my wife has had me keep tabs on her monthly cycle. I use an app called Clue to log daily data like period flow (from spotting to heavy), discharge levels, moods, and more. It sends me a notification when she is due, so I put out a pad for her on the dresser as a signal. I have really liked doing this task for her, viewing it as another part of my submission. Does anyone else do something similar for their kh or mistress?
