I've been using a mooncup for about 5 years. Not the same one, I acidentally flushed one down the loo, so this is my second. I've never had any problems with it until this month. It keeps leaking and last time I used it it leaked so much and so suddenly that the blood soaked right through my jeans. Just as I was picking ds up from school as well. I wrapped my cardi around my waist, which hopefully disguised it.
I had to switch to tampons after that. What's going on? Do I need a new mooncup, or was it just an extra heavy period that it couldn't deal with?
How often are you supposed to replace them anyway?
