Menstrual Cups?

Okay ladies, I just purchased a diva cup the other day and I’ve been excited to try it out and see what all the fuss is about. I’d done a lot of reading about it and I figured it’s a great alternative to the heaps of waste produced by traditional period products, but what I didn’t anticipate was how finicky they could be. Now I just tried it for the first time today, but I didn’t keep it in long because it wasn’t very comfortable which I’m pretty sure means it wasn’t in properly. I’ve reinserted it a few times since but it still doesn’t feel quite right so...

For those of you who’s used a menstrual cup, what’s the best way to get them in? How long did it take for you to adjust? If you’ve tried the softer vs. Harder kinds, which one is better?
