So where is your cervix? How far in? That will help you get recommendations. Otherwise I'd suggest generic things like pointing it to the side your cervix is on, pushing it up with your fingers or muscles and checking to see if you can feel your cervix in the cup. Lots of cuppers have leakage until they work it out so don't despair! And if the diva still leaks try a cup with a wider top so it can catch your cervix better. I'm not sure the tampon experience really helps you choose a cup, but it might mean your cervix is dangly. That just means practice with your cup and some loss of capacity which isn't your issue now.

I mean... I can reach with my middle finger.

... This might be a really dumb question or I just wasn't taught enough about this, but why does it need to be by the cervix??

Not BY the cervix, AROUND it. Think of your cervix like a faucet and your cup as, well, a cup. Right now it sounds like you are positioning your cup to the side/above of the faucet instead of underneath it. I have a dangly cervix that points to the left. When I first started using cups I was opening the cup to the SIDE of the cervix, rather than underneath/around it.

After putting in the cup sweep/stir around the cup to feel if it is open and if you can feel the end of your cervix, if you can feel your cervix you need to reposition the cup. Pull it out slightly, then shove it in the direction of your cervix.

Any cup will sit around the cervix, not way under it like the drawings show.

And just to be clear...the blood comes out of the end of the cervix (cervical os), which is why you want to cup to be around it--to catch the flow.

Ohhh okay.. So it'll "seal" underneath/around the cervix..?

This is perhaps a remote possibility, but for years my sister couldn't figure out why people used tampons because she always bled through them. It turns out she has a bicornuate uterus and two cervix...

It's actually not as rare as you might think - it occurs in something like 0.5% of the population

I mostly mention this because you mentioned tampons not working for you.

Skim/Read http://kuradi8.livejournal.com/ Hopefully it will help you through your learning curve. :o)

I think the "missing your cervix" part is correct. My cervix is pretty far to the left--meaning the hole points to the right--and I could never figure out why the left sides of my tampons were often dry but always had more blood on the right side. Same deal when I wore pads as a young teen. So your cervix is probably not pointing straight down. Do you remember if your tampons were often more soaked on one side than the other? Your cervix is probably toward the drier side and pointing to the soaked side.

Everyone else covered the other things I would've said :)

Okay :) thanks for the adivce.

So, how do I know where the hole to my cervix is?
Like mine feels like it's pointed more left (like por_que_no) but I've never felt the hole so I'm guessing it'll be on the right? So I just... have to shove it in towards my right side? haha.. and yes my tampons, like I had one in last night and yes the left side was a lot more bloody than the right O_o

Edit: Actually today it feels like it's right in the center

Yeah your cervix could totally move around as well, a lot of people's do. If you see more blood on the left sides of your pads/tampons you will want to insert cups towards the right. Once I figured out my cervix was on the left (thanks to a VERY pokey Lilycup stem that was stabbing my right vaginal wall on some days) I pretty much stopped having leaking issues.

congrats on making the change! :D im still a bit new to cups myself, but not new to finding my cervix. xD for probly the last few years (im 36 btw), before i made the switch, i almost always had to check where mine was every month, because it will go from pretty high, to soooo low. but i also have Gastritis, and from what my GI doctor told me, the tummy bloats pushes on other organs. kind of like a domino effect. if ones being pushed so will the others, which may have a hand in moving the cervix as well.
but i also bleed super heavy too, due to fibroids and cysts. but i just had to give up tampons unless they where super short, because my body would literally REFUSE entry, or push them right out. so the cup it was! xD and been so happy, thrilled even.
i had to come on boards and look all over too to see where its supposed to sit. for some i guess with longer vaginal canals, it can sit perfectly fine lower, and form a seal and catch everything. but for me, it has to be besties with my cervix. otherwise, its leak city. if you are bleeding heavy when you use it, (i use the diva cup v2.), remember just like tampons there will be residual blood after its inserted. not all of its going to come flowing out. just keep some liners around or light pads, or heavy, which ever is better for you. it will catch the left over blood.
sometimes youre cervix will feel like a pillow with a lil hole and a nub. xD just feel for the nub and hole, and aim. on my diva cup i had to cut the stem off. because when my cervix rides so low, i was feeling the stem on my g spot. hahaha. boy was that weird. plus not so comfy. i found at least with me, the more cramps and heavy it is, the lower it is. but mine seems to favor the back wall.i guess thats why they say some need to aim for the tailbone.
