...driving from Memphis, TN to Austin, TX (11 hours in a car!) without having to think about my period once. I was comfortable, had no worries about leaking, and didn't even need to empty my cup (which is great, because a lot of the bathrooms I stopped at were gross).
Take that, tampons!
For those who are curious, I was using a small Lunette. It still had plenty of capacity for this looooong car trip, and this was on my heaviest day. Just thought I would share my cup love! :D
