When should I consider buying a new cup? (Problem with my cup; hurts inside of me)

[fyeahjtv]

I'm 13, a virgin(not that it matters that much when I'm talking about a cup size, I guess.), I have a high cervix, and I'm just really tight down there. I just started using my DivaCup (size 1) and I think it might be too big for me, but I don't want to go out and buy another cup and possibly waste another $20 on something that has the same problem. It is very uncomfortable for me when I put it in me, and I'm not sure if it's part of the 'learning curve' that comes with using a menstrual cup for the first time, or if I didn't insert it correctly, or if it's just not a good cup for me. The cup does open up inside of me, but it opens like this; ) ( where it's kind of squeezed, but it does create a seal. Is that okay for it to be like that, or should it be completely open without it being squeezed?

I don't have any other problems with my Diva cup as of right now, just that it is very uncomfortable when inside of me. Also, it's very uncomfortable to get out and it stretches me alot, but I get the feeling it would be like that if I used any other cup(?).

Any tips on how to make it not as painful/uncomfortable? Could I try putting it up higher? What cup should I look into if I've tried everything and nothing has helped?Thank you for the advice in advance!
