Diva cup?

I’m very abnormal so I don’t get periods a lot, like I can go months without one and then get one out of no where. Also I find pads extremely uncomfortable and I’m too small for tampons, even the tiny tampons I can’t put in because they don’t fit. I’ve heard a lot about the Diva cup and was wondering about other opinions on it. Did you like it? Do they have one for “smaller” girls? Does it kind of feel like your free bleeding even though your not? I’m just so iffy about trying it. I don’t want to waste the money on it if it’s not worth it.
