Any notifications or widgets to help track periods (menstruation)?

My wife shares her period data with me via the iPhone Health app. I think if I checked it more often, I would be able to better understand her moods. But I struggle to remember to check the app.

Are there any widgets I can put on my home screen that can make this easier? Alternatively, is it possible to set up push alerts related to period tracking - like "hey, it's been 20 days since the last period ended; be prepared"?
