I'm 26 years old and have never been pregnant. Six years ago, I bought a Divacup and started using it. I followed the instructions that came with the cup, and inserted and placed it as the manufacturers said I should. I had light to medium periods, and the cup always leaked just enough to where I needed to wear a pantyliner with it. But I felt it was still way more comfortable than tampons, and of course less wasteful, so I stuck with it. And so it went for about five and a half years.
Then six months ago, I decided to get a copper IUD put in. That TOTALLY changed my menstruation. Suddenly I had strong cramps and was bleeding about three times the amount I had before. And my Divacup, for all intents and purposes, quit working. It never got full, but it would leak like crazy, and I gave up on it and was using thick cloth pads instead. Soon, I was frustrated with those too. I would always bleed through them, and getting all the blood out of the thick fabric when washing them was a pain. Plus, I had to have a huge supply of them to get me through my periods. I was about ready to give up and go back to using disposable pads and tampons.
So, a few days ago, I was in the middle of the heaviest part of my period, and I came here and started doing some careful reading on the "leaking" section. I found a discussion about how you shouldn't necessarily listen to the instructions that come with your cup, and for some women, it works way better to wear the cup up high and make sure your cervix is actually sitting inside the cup.
Well...it worked. I put my cup in, using some water based lube to make sure I could move it around easily, pushed it up high, and felt around the rim to figure out where my cervix was in relation to the cup. And it was completely outside of it - the cup was pushed up against my anterior vaginal wall, with my cervix behind it. No wonder it was leaking like crazy! I tilted the cup backward and made sure it was around my cervix, then made sure it was up as high as it could go. I've been using that technique for two days now, and it hasn't leaked a bit. It's also more comfortable to wear this way, because I occasionally used to have problems with the stem and grip rings irritating the opening of my vagina, even after I cut the stem completely off. Now I can't feel it at all. Another plus is, it doesn't block my urethra when I wear it up high, so it doesn't take ages to pee.
So I just wanted to say how cool it is that you ladies are such independent thinkers when it comes to menstrual cups. You solved my six year long problem with my Divacup! You rock.
