Thanks to everyone who suggested menstral cups!

I ended up going for a Fleurcup since I was told they are easy to clean and OMG is it ever. No little fiddly bumps and raised text! No little hollow tube at the bottom that's impossible to properly clean! Otherwise it works just like my mooncup did. I got the larger size since I am over 25 and it's been perfectly comfortable.

Here's the original post if you want to see everyone's suggestions.
