Some cups' instructions say you shouldn't use them with an IUD. Others say you can. Yet others say to ask your doctor. Personally, I think that's their legal departments talking, not their medical advisors.

Since you are already an experienced cup user, you probably won't have any issues. If you'd feel better about it, bring your cup with you and ask your Dr. S/He will probably tell you not to use any internal products for the first cycle or two, then go back to whatever you were using. Having your cup with you will facilitate "Show and Tell" when s/he asks, "What's a cup?" and will allow him/her to trim your strings appropriately short.

I've noticed that the cups with larger anti-suction holes around the rims are more likely to say that they're OK to use with IUDs. Decide for yourself whether you want to try to enlarge the ones on your Diva.

The thickness of the cup doesn't affect the suction? Do you know which brands already have larger holes?

My doctor who put the IUD in said it was ok to use tampons within a week after insertion so I'm sure a cup would be fine at this point (it's been over a month). I'm just slightly worried that I'll cause it to expel with the divacup specifically.

I think you're either prone to expulsion or not. I've had a long series of IUDs for many-many years and when I tried my first cup (it was a Diva) for the first time, I panicked and YANKED the cup out. It felt like I'd given my cervix a hickey! If that didn't dislodge my coil then NOTHING will.

I don't recommend it but you could "probably" do the same with no consequences.

There are a few here who have lost their IUDs but they are in the minority and a few of them have also expelled others for different reasons -- so I put them in the "prone" category.

I'm very curious about this. I really can't tolerate pads. I haven't worn them more than a handful of times in my life. I went straight to tampons and then the diva cup. Getting my IUD on Friday! I don't really know what I am going to do about bleeding if I have any...

Well you will be able to use tampons after like 3-5 days following insertion so you won't have to use pads for too long. I think I may post this question in IUD divas too for more input.

I also have an IUD and was told I could use tampons immediately after insertion if I wanted to. I asked about the cup, too, and the doc. said the same rule applied! Because doctors' recommendations vary so much, the general advice is to go with your gut and use what you want when you're comfortable using it. There's very little data on the subject anyway, and what does exist indicates no increased risk of expulsion for any particular menstrual product.

To answer the original question, I'd recommend sticking with the cup you already have. The biggest expulsion risk for IUDs is accidentally grabbing the strings when you remove the cup and yanking the IUD out. If you use a cup you have lots of experience with, you're less likely to make a mistake like that than if you're climbing the learning curve on a new cup. Unless you already have a lot of trouble breaking the seal and removing your cup, the Diva will probably be fine for you.

Thanks for the advice, I think I will just stick with it now to save some money and maybe try other brands out later on.

I think almost any cup can be used with an IUD as long as you kee pthe wall dented in and therefore keep the suction broken through the entire removal. And probably let it pop open early, and coaxi it up the rest of the way, so its not unfolding too close to the string and all...

Lunette is a good cup, I haven't had many problems with uber suction on that one. Also Fleurcup, and Yuuki, and MCUK, I cound those pretty friendly. I woul suggest somehting with good grips like the above ones, because the easier it is to grab and hold, the mroe control you have in removal, I think.

Maybe even a soft Meluna?

Thanks for the tips. Do you think I'm better off just keeping the divacup? Or trying one of the brands you listed?

Lots of great advice in the above comments. I personally use a Lunette and haven't had any problems. My strings are not very short either, but I don't want them shorter and it doesn't seem to be an issue for me.

There was a post back in August about this, with a link to the following article: http://www.familypracticenews.com/news/more-top-news/single-view/menstrual-products-don-8217t-increase-iud-expulsion/443f99a671.html

While it covers both tampons and cups, I'd probably think you'll be alright! Best of luck!

I am not sure the brand has anything to do with it. I've got a Mirena and have used cups exclusively (LadyCup and Yuuki) - even when the doc softly recommended against it. (Which was for the days immediately after insertion.)

Most of the time I remember to do it the *right* way and break the seal, that isn't always the case - and so far no problems. I suspect it would take a heck of a blast to dislodge my IUD. :)

Not sure that I answered your question, but good luck!

Interestingly, I've had no trouble with the Divacup and my IUD (I think the length helps, so I can pinch the base without risking grabbing the strings), while I had huge problems with the old medium meluna (which sat right on my cervix). If you're happy with the divacup, I wouldn't change brands.

I went for my ultrasound 3 weeks after insertion today. Everything looked GREAT! Awesome news since I'm on my first Paragard period post insertion and I'm using a DivaCup for my flow for the first time. I was really worried about expulsion. The ultrasound tech told me that expulsion was rare and that it's pretty difficult to pull it out. She said you pretty much have to yank on the strings to get it out.

Anyway, my period isn't terrible. My flow might be heavy, but with the DivaCup, I am not leaking at all and I just make sure to break the seal before I empty it. I love the DivaCup! No leaking is a blessing. I've leaked all of my life because I've always had heavy periods.
