Well, my period finally started again, so I got to measure the distance from my introitus to the near side of my cervix. 35 mm!! No wonder my Diva hangs out so badly (even inside out)! And to think, when I first discovered this site I thought my problems were all related to diameter and Kegels (or relative lack thereof)!

I think Day 3 of my period is when my cervix will be at its lowest, since that's been when I typically have to give up and go to pads. I'll have to remeasure....

I already have poured over and agonized over the size charts. Now I just want to collect some data! If you have inverted your cup, how long is the inverted length? FYI, the large Diva goes from 57mm to 51 or 52mm. It would be awesome to have this data all in one place for other low-riding women.


-----------Edit:--------------------
Summary of inside-out lengths (a work in progress):
Large Diva     57mm -> 51mm
Small Diva     57mm -> 

Large LadyCup     53mm ->
Small LadyCup     46mm -> 43mm

Large MCUK     50mm -> 
Small MCUK     50mm -> 43mm

Large Lunette     52mm -> 
Small Lunette     47mm -> 43mm

Hey! My cervix is lowest on my 3rd day as well, and mine is about 33mm in (about one knuckle on my middle finger--negligible difference from yours, I'd say). I actually use a regular-size small Lunette. I haven't flipped it inside out or trimmed the stem or anything (the stem does hang mostly outside my body by day 3, but because it's flat, it doesn't bother me). My cervix fits neatly inside the cup too, so the cup itself doesn't poke out.

I had a hell of a time with the Diva as well. I tried it out before I knew about this community, so I didn't know there was such thing as sizing, and was also convinced there was something wrong with my anatomy or I needed to start kegeling 24/7 in order to be able to use a cup properly. Augh! What a nightmare! Even though my cervix fit inside the Diva as well, the Diva was still so long even inside out or stem trimmed completely off that my cervix would push it right back out when it descended to its lowest.

I'm interested to hear how many other super-low cervix gals we have here. Lots of people seem to post about how omg!low their cervices are, but so far as I can tell, most of them have nothin' on you and me. ;)

I think I saw a few knuckle measurements in here somewhere, but I think we're officially the first to supply data. Makes it more meaningful when I look at the size charts and see the lengths laid out next to my 35mm measurement!

Keep it coming, low cervix ladies, more measurements!
melissa569melissa569 on April 8th, 2009 10:24 am (UTC)
I'm in the U.S., so we measure more by inches. But I'm expecting my period any time now, and I just checked where my cervix was earlier this evening... Its the lowest its ever been-- I got just past the first joint/knuckle on my finger, and I felt it! Yikes! lol. Practically right at the entrance. But luckily, there is a space all around the sides of it, that goes further back, which a cup would fit around.

Well, I live in the birthplace of the United States (Philadelphia), but they DO sell metric rulers here! ;-)

I decided to give my figures in mm 'cuz we have an international audience, and the size charts are all in mm. (I also use use metric every day in my line of work.)

But yeah, give us your data! And if all else fails, we can convert inches to mm. And your experience is super relevant, since you have a lot of cups to compare.
melissa569melissa569 on April 8th, 2009 09:56 pm (UTC)
I'll see if one of my rulers has those measurements on the back... It might...

When I turned my Diva inside out it was about 51mm. I gave up on my Diva a long time ago though and started using a Mooncup UK with way more success for my low cervix.

My cervix is lowest when my flow is heaviest, during the first two days of my period. I don't measure it every time but I did during my last cycle and it was pretty much right at my vaginal entrance. My finger only went in less then halfway before I could feel it, about 30-35mm.

My cup doesn't hang out though, even when my cervix is that low. If I put it in just right my low cervix actually rests right inside of it so I can get the cup further in (and feeling a lot more comfortable). However, I could never really get my Diva to do this right, inside out or not, which is why I switched to a different cup.
redhead74 on April 8th, 2009 03:08 pm (UTC)
See, this is what doesn't make sense to me. If an inverted Diva is 51mm, and an uninverted MCUK is 50 mm, why would the Diva hang out but not the MCUK? I mean, it's not like ONE mm should be a big difference.... I think I'm missing something here. Something about the shape or the stiffness or something.
Katzhukora1 on April 8th, 2009 04:31 pm (UTC)
I think it may have something to do with the Diva being very long and narrow-ish in shape, whereas many of the other cups (MCUK included? I don't own one so I can't say for sure) have more of a bell-shaped "hoopskirt" profile, so even if they're comparable in width at their widest point, their taper from the widest point to the stem is much more extreme over a much shorter portion of the overall length. This would make it easier to fit a roundy-moundy cervix inside than it would be to fit one inside a longer and overall narrower Diva. That's the theory anyway. ;)
Jonilittle_joni on April 8th, 2009 08:20 pm (UTC)
Agreewith zhukora1 on this. Plus I was going to say I had real problems with getting my Diva to pop open consistently and with the suction. For some reason it did not want my cervix to be in it but rather shoved it to the side which a)was really uncomfortable, b) made it slide down too far, also causing discomfort, and c) created major leaks.

The Diva is also less stiff then a MCUK, causes more suction then an MCUK, and is shaped slightly differently. One or more of these differences probably made a difference to me...I have no idea what about the MCUK works better, it just does so I go with it. :D
redhead74 on April 9th, 2009 05:51 pm (UTC)
I think I come away from these discussions more dizzy half the time....

Stiffness: MCUK is stiffer and therefore works better for you than the Diva, whereas someone else told me (tntmommy, in another discussion) that she had a low cervix and the LadyCup worked best for her (than the Diva) and it is super soft!

Shape: MCUK has a flange and works better for you, whereas zhukora1 uses a lunette which does not, but both have worked better for you two than the Diva.

The only thing I'm getting out of this is that it doesn't really seem to matter what I choose, as long as it's not a Diva!?!?!?! ;-)

Maybe I just need to close my eyes and click and find out in two weeks which one I bought!

My small MCUK and small LC are both about 43mm inverted. (Since the Ladycup doesn't have a highly built-up base, inverting it doesn't make much difference.)
redhead74 on April 8th, 2009 07:21 pm (UTC)
Well, that's only 3mm off the small LadyCup, but a whopping 7mm off the small MCUK!

I'm curious to know, since I hear the LadyCups can be pretty slippery to remove, whether it is any easier to grip when inverted? And how about the MCUK?

Thanks for your input!
Ashatenlegspider on April 8th, 2009 07:51 pm (UTC)
I've never had trouble gripping my cups, but I assume any cup would be harder to grip when inverted, since you lose the ridges or bumps.
redhead74 on April 8th, 2009 09:12 pm (UTC)
Oh no, I think my Diva is easier to grip inside out! The ridges are gone, but because the silicone is really thick at the base, when you squeeze the inside-out cup it doesn't squish into a "V" but rather into a kind of a square at the base. Kinda shaped like this: )_( instead of: \/

Hopefully that makes sense... Anyway, that gives me something substantial to hang on to, and makes it really easy to rotate it, release suction, etc. But I assume that a cup with really soft or silicone at the base would squish into a slippery V shape.

I turned my small Lunette inside out, and it shortened it from 47mm to 43mm. You can see pictures here: http://community.livejournal.com/menstrual_cups/1550290.html#cutid1
redhead74 on April 8th, 2009 09:04 pm (UTC)
Wow, I missed that! Thanks!

lowest cervix
Well, I looked up the average, and it's strange. Many sources say that the average distance from introitus to cervix is three or four inches (7.5 to 10 cm.), but the sources that cite actual studies place the cervix at an average of 6.23 cm from the introitus with 4 being on the low end and 9 being the longest. The studies were done on healthy women between 20 and 45 y.o.
Mine's between five and six cm. It used to be farther back, but I just had a painful pap that caused me to push the speculum out from inside, along with some of my uterus. I was wearing a size one diva before. Now, I am not sure what I can wear.
