i got my period yesterday so, as usual, i popped in my cup. about two hours later im leaking like crazy, so i think, no big deal i probably forgot to check that it was sealed so i go and reinsert it. this time i check to make sure that it's sealed (it is). but yet again, a few hours later i start to leak. this continues for the whole day and i just think to myself.. it is the heaviest day of my period, maybe its just that, tomorrow i won't leak. well, what do you know, i wake up to my cup leaking. i go to empty it, thinking that surely it's full, but no, its not even halfway. i've been using the origami fold (the one i always use) but that doesn't seem to be working so this morning when i reinserted i used the punchdown and that seems to be working (so far). if this doesn't work, well then i don't know what else to do.  all the times i've leaked i've checked that i got a seal, and i have. the only unusual thing i'm noticing is that when i insert, it's sealed but when it leaks and i go to take it out, it's like the seal broke by itself, causing the leak. is that possible? am i doing something wrong?
