My friend's daughter recently started her period (sorry guys- you probably didn't want to read that). Usually they start off irregular, so she did not have one the next month. So she asked her mom (my friend) if that meant she was going to die.
Since my friend is a good mom, she answered honestly and explained how the cycle takes a while to regulate.
I'm thinking that when my time comes I may tell my kid that missed period = death
Have a good day!
