Wrensmom, I'm so glad you asked about this.....I've never heard of this before - I need a Diva cup a.s.a.p!!!! I'm supposed to do a MS150 Training ride on Sunday, and may need to cancel because a visit from "Aunt Flo". I'm perimenapausal, and it's a huge issue.
I just did a search on the Diva site, and they sell them at Whole Foods!
Thanks so much for the information, I'm going to try to find one of these today!
