Greetings! I'm just finishing off my third cycle with the Medium LUB. After trying out 7 or 8 cups, it's really satisfying to say that I've found my goldilocks. The cup has amazing capacity, seals extremely well in my body, and can be worn leak-proof overnight and on heavy days.

That is not to say I have never experienced a leak with the Medium LUB! I have! I wanted to share my discoveries on avoiding leaks as they may be helpful to people using the LUB, and possible even other cups. So...

Constipation. I was traveling recently and had to deal with my heavy days while in transit. Airports, planes, poor nutrition, lots of stress, limited access to toilets, and dehydration from long hours in a plane cabin. All of this will make you very constipated! Aside from being uncomfortable, I had a theory this may be affecting my LUB's ability to seal. I experienced several leaks over these days in transit.

This cycle (back home), I took care to eat plenty of fiber and drink lots of water to prevent any constipation. Without travel-related constipation, the cup sealed fine and I was leak-proof the entire cycle.

If you're trying to trouble-shoot a leaky cup, consider constipation as a factor that may be affecting the cup's seal.

Another thing I tried for this past cycle (which was entirely leak-free) was wear my cup inside out exclusively. I have a high cervix, and the length of the LUB is not a problem for me, but the texture of the inner cup is sooooo smooth. I had NOT ONE LEAK! No slobber whatsoever. It was incredible. I usually wear a pantyliner overnight or on my heavy days, but there was really no need this time.

I'm trying to figure out why inside-out may be preventing any and all leakage. If you have any theories, I'd love to hear them! Mine are:

1) Less pronounced rim. A flipped cup has a less-pronounced rim, meaning less difference between the holes and the rim. A pronounced rim might create a "tenting" effect in the vaginal walls and hold them too far from the holes to form a proper seal. This means that small amounts of menstrual fluid may be leaking from the holes. I suspect that most of my cup-related spotting has been due to leaking from the holes. For me, a less-pronounced rim helps the cup form a better seal. Fleur (which has a large rim) would start leaking through the holes at the halfway point. I have not tried to use Fleur inside out to see if this would be prevented. I suspect that folks who experience leaking from the MoonCup may be having this problem, and should switch to a cup with a less pronounced rim.

2) Okay, I really do not have a second theory.

This is interesting! I have IBS and I have issues with my cups getting crushed during my period because my vagina oddly compresses a lot as my cycle goes on. Maybe constipation is causing it.

It's totally possible! I don't suffer from constipation when I'm drinking enough and eating healthy food, but my husband has a lot of IBS-type problems. I'm actually building a stool this week to convert our standing toilet to a squat toilet to see if that helps (there's a model on the market called "Squatty Potty" if you're interested to see what it looks like). There's good evidence that squatting for bowel movements helps alleviate constipation and IBS symptoms. Interested to see if it works!

I can definitely say that constipation affects the fit and sealibility of my cup.

I'm actually half Taiwanese and those are all over the place there, so I have plenty of experience with squat toilets lol...I had no idea they helped with constipation, I researched it and it makes sense! I have to keep that in mind.
