I recently found myself having to use tampons for a few days as I was without my Mooncup (I may possibly have boiled it dry by mistake!) and what a nightmare - they were useless! I was changing them every 2 hours at least and between those times, I was constantly wary of leaks - I wouldn't consider myself a particularly heavy flow person. And then there's what to do with the used tampon/applicator; I'd forgotten about having to decide if you can throw it down the loo (let's face it we all do/did it!) or if you need to put it in the (usually not very) sanitary disposal bin. And that's without having to think about all the other hassles with tampons like actually remembering to carry some around with you!
I was overjoyed to be back using my Mooncup yesterday evening. I'm back to only having to worry about it twice a day and my (and my office's) drains are once again 'safe'!
One quick tip/thought - I'm 32 and have given birth twice vaginally (although admittedly both times pretty quickly and with very tiny babies) but I am finding the smaller B-size cup far more comfortable than the larger A-size cup that I assumed I'd need by now. I certainly don't seem to be having any leaking issues. I just say this in case anyone else thinks that they should probably be on the larger one but it feels a bit uncomfortable, don't assume that the smaller one would be too small based on their age or how many babies they've given birth to.
Oh - one last thing seeing as I'm here... be warned that Mooncups *can* dislodge coils - mine did and I thought I was being fairly careful. Of course, it might not have been the Mooncup but the suction was pretty strong at times so I think it may well have been that.
