I've heard so many people say their doctors don't even know what a cup is, or think they're weird, so I was expecting a similar reaction and gearing up for an explanation. However, my doctor grinned widely and nodded enthusiastically.
'They're great, aren't they?' she said. 'Really good. Sometimes tampons don't help.'
Not only did she know what a cup is, but she likes them and seemed really chuffed that I'm using a cup. Heck, from her reaction, I'd say she's probably a cup user herself. That, in addition to the really good rapport I had with her, means I'll definitely be seeing her again in the future. :)
