My mum and I had a shared period calendar when I was a young teen and still getting used to tracking my cycle, she hung the calendar and pen in the bathroom to model how I could track my cycle in a diary as I got older.

We invented a key/symbol system so the calendar wasn’t intrusive for my brother and father to see, and one of the symbols we used for the luteal phase was a sort of hourglass ⏳, it was originally my mums poor doodle/sketch of a panty liner to indicate “you might spot a bit this week” but it looked like an hourglass so I joked that symbol meant I’m “just waiting for the storm to arrive”.

It was the perfect symbol for me, because when people ask about the tattoo, and I don’t want to go into the real reason I say “it’s a visual reminder” and if they ask more I can say “it’s an hourglass, because there’s only a little time LEFT, it’s on my left hand - I get my lefts and rights mixed up. Plus it reminds me to put my watch back on after I get dressed, so it helps remind me of a lot of different things”
