Well I seem to have a bit of a mystery which I hope you can help me to solve. I've been using the Diva Cup for over a year now with no problems at all until this month! I haven't been able to get the cup to catch a single thing. It's just leaking like crazy!! When I get the cup in it seems to be perfectly open and smooth but I don't seem to be able to get it to seal. I can turn it around no problem and like I said before it seems to be open perfectly. This may be a stupid question but can heat affect it at all? We're experiencing temperatures in the 40's (celsius that is!) over here at the moment and I was wondering if that could be affecting it? I'm very puzzled by it and I really don't want to have to resort back to using tampons after all this time!
Thanks in advance.
