Update Edit: Used Size 1 all day but had a few leaks. Discovered the 7-Fold on this forum and that had been working wonders with insertion. Just switched to Size 2 tonight because 1 kept slipping? Could it be my size changed since my flow started yesterday? I'm cool with using Size 1 AND Size 2. Either way Divacup far outperforms Instead (in my book anyway). Although I would use Instead during sex.
Update Edit II: I just finished my first cycle with Divacups. I ended up switching back and forth between the sizes as my flow changed. Also, REAL IMPORTANT, each cup is popping open very easily now. I wish I'd known that the silicon is stiffer in the beginning because I believe that was the problem initially for me. It should be included in the directions.
Also (and I am thrilled to report this), I've gotten through my very first cycle with using ZERO disposable products! Previously, I'd been using Instead & cloth pads but would always supplement with a tampon and/or disposable pad or two. No more!
