After reading people's experiences in different communities like this one and naturalliving, I've finally decided to buy a cup. The Diva cup seems to be the one most people compliment, so I was initially thinking of going with that one.
I'm 29 and have not had children. Since I'm so close to thirty, I'm thinking the larger size Diva cup might be best, but I'm not sure. Part of me thinks that buying the larger size would be erring on the safe side to prevent leaks, cover me during more sexually active times, and cover me for the future. But on the other hand, I wonder if there are drawbacks to using the larger one unnecessarily. (Could it be uncomfortable to the point it's unmanageable? Or do people who deal with discomfort tend to have problems no matter the size? It's hard to tell how much of a difference size makes.)
I went through the memories and entries with the "size/size issue" tag, read entries by people frustrated by size issues, and found advice to switch to the Mooncup or switch sizes for a variety of reasons, and now I'm a little intimidated. I don't want to throw a ton of money away on this, so I'm also going to ask how returns work or if anyone has links to sites that offer returns. (I didn't think you could return a product like this, but I read someone mention it somewhere.)
Essentially I'm trying to gauge what would be a safe bet. Buying a cup is a big step in and of itself, and I'd like this to go as smoothly as possible if I can help it. I could really use some guidance on size (and brands as they relate to size). Thanks very much in advance.
