bladder pressure, shifting and leaking (sort of?)

hopefully im making this right! ive never posted on livejournal before (i made an account just for this) but i bought a small ruby cup a few months ago, ive been using it for maybe 2 or 3 months now and no matter what i do it doesnt seem to catch everything. i am SURE it is sealed completely, every time i check its opened completely and every time i remove it i need to break the seal. it does catch most of my blood but sometimes (usually) ill get spotting when i wipe and it will be outside the cup.

another issue ive been having is that it always feels like i have to pee. i already pee a lot as it is (i think i have a small bladder) but it seems to be putting pressure on my bladder and i even have had to remove it completely in order to pee once.

also, no matter how deep i insert it it always seems to end up very close to the entrance of my vagina. i have completely removed the stem because of this and tried inserting it multiple different ways. i usually use the 7 fold. if anyone has any advice for any of these issues i would be so grateful. i really want cups to work for me.
