Urologist?

I Have An Appointment With A Urologist in Lexington,but im from southeast Kentucky
im kinda nervous, what do you think they will do?
I had to get checked down there at my local doctor, and I cried really hard, I felt really nasty, I'm Afraid if I...

dont shave they will think im nasty, im 12 and had my period for almost a year...Im going there because I get the urge to pee every little while and its like I pee but I dont, and I know I pee out of the right place, but after this happens when I have to hold it, it comes out a different place, and I'd had to be took home from school about 4 times for peeing on myself because of this, and it really sucks when im on my period when this happens because I get blood all over me...and the stains hardly come out of my clothes.
soo um got any ideas on what could be wrong or what the doctors might do?
im clueless. :/

go and see a lady doctor may br a gynochologist,if you are really scared and emmbarresed.. there must be a urine infection and sometimes can be treated through drugs...

Thanks for the advice, I researched it a little more and it is pretty much describing Interstitial Cystitis. But it doesnt hurt...unless I have a UTI which I get frequently because I have to hold it at school because I have to constantly go every 10 minutes.
