I got a menstrual cup because I felt guilty every time I threw away a pad or a tampon and I was tired of worrying about what time it was and when I was due to change tampons. Almost a year ago, I ordered this because I wasn't for sure which size I was (I've actually ended up using both pretty regularly). I did have to cut the stem on the small cup, it's worth noting, but the smaller cup does come with a longer stem. And you may not have to, if your body is okay with that length of stem. While the first few months were full of learning curves and getting my body used to the cup, I quickly learned that menstrual cups are AWESOME. They're so much more comfortable than tampons (it's gotten to the point where I find tampons uncomfortable now), and they're super low maintenance since you only have to change them twice a day. Moreover, you can sneeze, cough, hiccup, or do anything along those orders that would dislodge a tampon and still be okay! The only major con that I find with menstrual cups would be the fact that they are much harder to use when one has long nails. I am not a person who can keep my nails long, and I got my nails done for prom. What I had forgotten, though, was that I was due to get my period. I could not change my cup with such long nails, so I had to wear tampons for the first time in 10 months. To those who are new to menstrual cups, you will get used to them, you just need to trust the process. It will feel odd at times, but once you get over the initial learning curve, you'll be hooked. One final note is that if you don't feel comfortable using toilet paper to clean out your menstrual cup, there is a menstrual cup cleaner and sterilizer out there called Emanui. I'm still on the fence about ordering one myself, but if you're curious, I just thought that I'd point it out.
