I always took a messy period for granted... but it doesn't has to be messy!
The first time using the cup was quite hard. I didn't put it in right, so I leaked a bit (was only once though, after carefully reading the instructions, I got it into the right place). Getting it out was also hard at first. But after a few days I got the hang of it.
If you bleed a lot, you need to change your cup regularly, but in the end you can leave it in for almost an entire day without even noticing you're bleeding. If you change the cup in time, your hands won't get bloody at all, in fact, nothing down there will be bloody! It's perfect. When I'm on my period, I always feel like there is an odor around me, but I don't smell that while using the cup.
You can do every activity with this cup, because it won't leak.
And if you don't get it in right at the first time, read their tips. They want you to have a good experience, and that surely is possible. So don't use it once and reject it... because it's a game changing cup! You'll love it.
