She may have accidentally shoved a little stick or piece of grass or something up there. You can gently flush out both sides with sterile saline solution. Then just keep an eye on her. If you think there's something wrong, you should take her to the vet.
What about country or state? I understand not wanting to give out specific information - and if you were my child, I'd probably insist - but maybe consult with your parents about providing at least a general geographic area so you can receive vet recommendations. Or, look at the recommended vet list with your parents that is located on this forum (if you're in then US). You'll likely still have a drive to get there, but your parents may be willing to take you if you explain. Try Yvonne's recommendations first though. A vet may not be needed.
