I've been reading this forum for the past few weeks. This is my first period using a cup, and I just finished my second (terrible) day. I'm using a small Diva Cup, which may be my problem since it seems like my cervix may be a little low.
Well, yesterday went fine. no leaks except for overnight, which I was a little annoyed with. However, today was a total disaster. I got the cup in, to be best of my knowledge, positioned perfectly. My cervix definitely wasn't peeking out at any point, and the cup was definitely completely popped open. But, by mid-morning (I made it through my 2 hour class, thank god), I could feel the cup coming loose or something (felt like air was escaping? bubbling?), and I'd have to rush to the bathroom. This happened constantly for the rest of the day, in under an hour every time. My period is not heavy, by any account. The cup was always less than 1/3 full, but I was wearing a pad as backup and I was definitely bleeding a LOT into my pad. Like just as much as was getting into the cup (that may be an exaggeration but.... yeah it was still a lot of blood). Also, just to note about the amount of blood, I get really freaked out when I feel blood coming out of me because I normally just wear tampons and liners, and I can never really tell how heavy my flow is so I'm hypersensitive to blood flow and can get to the bathroom in record time. So it's saying something that blood got on the pad at all, considering I went to the bathroom the moment I noticed blood was leaking. Meaning it must've been like a fuckin' geyser in there.
By the evening, I was so fed up I switched to a tampon. The tampon lasted me about 3 hours and I only took it out because I was so used to feeling like I was going to bleed all over the place and 3 hours had become a "long time" in my head. So I probably could have left it in for a good 4 and been in the clear.
What gives? I'm positioning it correctly, it's fully opened. I've read a ton of threads but I don't see many people having leaking problems to the same extent. I mean, my period is pretty clot-heavy, but I can't imagine that would cause such a problem.
(oh I'm a 21 year old college student and I use o.b. tampons so I'm used to shoving my fingers up my vag. Also new to LJ so I have no idea what I'm doing)
