“I have cramps.” – our 3-word policy on menstrual leave

My only question is if it is required that they mention 'I have cramps' explicitly publicly. Not sure if their menstrual cycle is anyone's business. There's also no reason for it to be taboo, but not sure where the balance of 'it is nbd, deal with it!' vs 'I do not really want to broadcast this information to my teammates' is.
