I'm planning on buying my first menstrual cup today. Any recommendations or warnings?

There are so many to choose from! Have any of you had to buy more than one before you found one that fit?

I think I have a short cervix as determined by myself, and I'm having trouble figuring out the length I need including the length of the stem. From my understanding, the stem can be trimmed, so I suppose this isn't so much of a problem.

This website is really useful in helping to compare the different brands.

Personal anecdotes are welcome! :)

edit - I just ordered a divacup from iHerb.com and they gave me a referral code people can use to save $5.00 off the purchase price, so you can get one for $19.70 + $1.50 S&H. The code is TIJ420 and anyone can use it.
