I know this thread is old, but I’ll always add my +1 thumbs up to a cup thread, because I think they can be a game changer. And, I’m pretty sure I originally found out about them on here, so… keeping it going I guess.
I suppose I lucked out that the first one I tried (Diva) fits me well. Extra lucky, I guess, since I’m pretty sure they were my only choice back then. I will note I still prefer the “Under 30” model even though I’m halfway into my 30s now. The “Over 30” doesn’t leak or hurt or anything, just not as comfortable to insert I guess.
When I first bought it, it was largely with riding in mind. Not because of flow or jostling or anything, but because I hated going out for a ride or lesson knowing I might get my period any time now. So the idea that you can put it in safely before your flow actually starts was a big selling point. It’s still a big plus to be able to do this, no matter where I am going!
Then I became a groom and thank goodness for the Diva Cup. No matter what your flow, it’s going to decrease how often you need to attend to things (I think I’m pretty average. I typically need to empty 2-3 times day 1, maybe once day 2. Go all day after that). This extra capacity is key at a horse show! Sometimes we are literally too busy to go to the bathroom exactly when we’d like. Plus, I find many horse shows have a “real” bathroom somewhere and a bunch of porta-potties everywhere else. I much prefer being able to wait for a real bathroom whenever I can.
I’ve had leaks over the years, but usually notice pretty quickly. They are from inserting it not quite right, or, on occasion, overfilling, because it’s so comfortable I forgot my period. So, I don’t think I’ve ever had a problem while riding. I suppose more than luck, this would be because I am more thoughtful about emptying knowing I’m riding, and yet, catch any “in crooked” issues by the time I was ready to get on.
