I clicked love it, but actually i love the concept best....
In 2000 (holy moly, i've been using these things for a DECADE!) my friend bought me a natural rubber Keeper. I loved it. No more mess, no fuss, i DID find it made my cramps worse, BUT i had those worse cramps for 4-6 hours instead of 24-36 like i do without the cup, so for me it's a good trade (ymmv).
In 2002 i began to get thrush symptoms during AF every month and it took me 3 months to figure out...i was getting a rubber allergy. So off i went and got me a Divacup (medical grade silicone). The Divacup is (i think) the l-o-n-g-e-s-t of menstrual cups and i'm not very, um, deep, so i cut the stem right off, otherwise it poked into me when i sat down (not comfy!).
I had a baby in April 2006, but my pre-baby diva still worked afterwards (i am the "lucky" one who got AF back 6weeks PP despite EBFing), so i never got a new one. In December 2006 i got a Mirena fitted. The guidelines say you can use the cup with the IUD/S BUT you have to be careful when removing it, since the suction could theoretically draw the device down into the cervix (which would be OUCHY painful and mean you'd have to get a new one fitted). So i stopped using it for 3 months to give my IUS time to "settle in". By the time those 3 months were up my bleeding was so light (with the Mirena hormones) that i just ran myself up some light mama-pads on the sewing machine and put the cup away.
In May 2009 i had my Mirena taken out and my Diva worked great for the 2 early miscarriages i suffered (and meant i could stay home and monitor what was out and what wasn't, rather than having to go in for a D&C, for ME a bonus as i like to miscarry at home with my loved ones, i've done it 4 times and i know how to weather it now).
In June 2010 i had DD2. My 2nd baby, 2nd daughter and 2nd delivery with a direct OA presentation (neither one turned to deliver their shoulders, coming out with them side to side instead) and my 81mins (total, including 20mins 3rds stage!) labour and 6mins 2nd stage....well that pre-baby cup ain't gonna fit no more!
I had a copper IUD fitted at 10weeks PP, so once again i was waiting for the IUD to settle, but hadn't had AF yet anyway.
So last month, when i got the shadow of AF back (only a bit of spotting but full on PMT/dip in supply/low cervix action) i went out and bought myself a lovely new post-baby cup. It's a mooncup, not a diva - moons are shorter (great for me, especially since there seems to be a bit of sagging/rectocele going on in there still, especially at AF-time!) but i still cut the stem right off for comfort. I used it for 3 hours last month, in a weird way i'm looking forward to using it in the next few times.
So, as a 10-year user of the menstrual cup i LOVE them. For me they are convenient, mess-free, comfortable and make me feel very empowered as a woman (not having to wear a pad smeared with blood, which i always hated, don't have to worry about an odour, not concerned about TSS (which CAN be a risk but has never been associated with cups like it has tampons), not having to shell out more and more money every month for the privilege of being female...i could go on).
Things i have learned:
It IS ok to put it over your cervix if that's how your anatomy works (the brim behind my pubic bone IS over my cervix, i'm about 3inches deep at AF time, about 6-7 at ovulation time). It IS ok to remove, tip to empty, and reinsert without washing or wiping - once in a filthy train toilet somewhere crossing Eastern Block Europe i had to pee on it to clean it (my pee was the most sterile thing for about 3 miles!) and it was fine. It is OK to cut the stem right off. It is OK to turn the whole thing inside out if that makes it more comfy. It is OK to experiment with it.
So there you go, i love it!
The only thing i would say is that with the pre-baby Diva i would very occasionally (twice a year) feel like i was getting a UTI if i wore it overnight every night, because my anatomy is so crowded that the brim rests pretty heavily on my urethra inside and sort of squashes it against my pubic bone. I get the same effect after every single exam i have that needs a speculum, it's just how i'm put together. I never GOT a UTI, i just felt like i might be, and wearing a mamapad for a night or two always completely rectified the issue.
