I've been using a diva cup for years and years and I love it, but the last few months I've been noticing my vulva getting really really itchy around my period. At first I thought it might be my reusable pads (I use them for the first few days with the cup) so I tossed them. This month I thought I was getting my period so I popped in my cup (I wasn't after all) and after a day or two I got really itchy again. Anyone experienced this or know what this can be? Google says a silicone allergy is rare or nonexistent. I really don't want to go back to tampons and I could just use cloth pads but I really like to keep it internal. Thanks!
