Always forget I get periods

Today I see blood and it all make sens. Why I was emotional yesterday, why I wanted sweets (alcohol), why I was watching baby videos and reading data about children when I can't stand them the rest of the month. All these signs every month and still I forget I am about to get my period. It is like a revelation/surprise every time.

Did I install an app to track them... yes.

Did I remove all notifications not to get distracted... yes
