My cup has been leaking like crazy for the past couple of days. I'm not doing anything noticeably different. There's a good seal and it has definitely "popped" open every time I've inserted it (and I've done and redone it several times), but it's still leaking. It's not full whenever I take it out, and the leaking starts within a half hour of inserting the cup. I've got a light period and usually I only empty my cup once a day (twice on the heaviest day), and even then it's almost never full. I'm 20 and nulliparous, so I doubt it's a size issue, especially where I've never had any issues before.
I have a little spotting with it every month (I've always assumed it's just blood that made its way partially down my vagina before I insert the cup), but only on the first day of my period, and never enough to really warrant wearing a liner. I've gone through two or three liners a day this period! It's really quite annoying...
Any suggestions as to why this is happening all of a sudden, and/or how to fix it? I looked a little bit in the memories, but nothing seemed to jump out at me as a possible cause/solution.
