FWIW, I've been happily using my large Lunette in combination with Paragard for the past 1.5yrs.

I've been working on a page talking about this, mainly collating the information given by some of the menstrual cup companies http://www.femininewear.co.uk/iuds-24-w.asp
I hope it helps

Thanks for collecting that!

Awesome!

I just got my Mirena Tuesday. (25, NP here.)I use two cups myself--a size 1 Diva and a M Meluna Soft. I actually used my Meluna the night after my insertion for the (minor) spotting because a pad was rubbing too much, and I didn't have any problems with it.

You might want to take a look at the iud_divas comm here if you haven't already; there's a cup tag I know. Personally, I'm not concerned about it. I remember there being a discussion about a study that showed cup use did not significantly increase the rate of expulsion with iuds--it did very, very slightly. I think that if you're familiar with your cup and just be cautious you'll do fine.

I've seen a few companies recommend cutting the string short for use with cups, but I personally don't want my strings shorter than they are right now (3 cm) because there is a correlation with short strings potentially (again, not with an overwhelmingly large majority) poking male partners during sex. As my iud settles I might decide to get the strings cut a little, but I would much rather them be long enough to curl around my cervix than too short and risk them being pokey.

I've been using a large Lunette with my IUD (Paragard) for about 1 year now - no problems!

Some cups say you can use them with IUDs. Others say not. And yet others say to ask your doctor. I think that's their legal departments talking, not necessarily their medical advisors. Since you are already an experienced cup user, you know how to break the seal for removal so theoretically, you should be able to use any cup with your IUD.

To remove the dingy-ness, give it an overnight soak in some hydrogen peroxide. And since you think the seal is hard to break, try enlarging the anti-suction holes around the rim of your Diva.

I have no idea where I read it, but I thought peroxide harmed the cup? Maybe I I just dreamed that :P How do you enlarge the holes? I hate those stupid tiny holes!!!

Here in the US (this is an international list) the hydrogen peroxide we get from the first aid aisle of every market, drug store or discounter is only 3% strength. And just like soda loses its fizz, that strength of H2O2 turns to just plain H2O in a short amount of time -- so you "can't" over-soak it.

I no longer have the link/bookmark but somewhere in these replies is a chart that says that medical grade silicone's resistance to much higher (50%+) concentrations of peroxide is "excellent" and only falls to "good" at near-100%.

Some have had luck enlarging the holes with drill bits, small scissors or body piercing tools.

The Ladycup has a soft bottom and a firm-ish rim, while the Lunette is rather firm all over afiu. The Lunette looks easier to grab. I'm not sure what the general consensus was on which kind (soft or stiff) is easier to remove, perhaps this is something users could comment on ?

In case you are interested, I have a large Lunette cup for sale at mc_sales.
