What can I take?

Kelly
I think I have BV, it's been like this for months now and I have always wondered if it's a bacterial infection or yeast infection but after reading a thread today iv concluded it must be BV
My symptoms are , white sometimes yellow thick discharge and a lot of it ... All the time, I sometimes get an extremely bad smell , not all the time though and it doesn't smell like fish , I expecially smell after me and my boyfriend have unprotected sex, it sometimes hurts to urinate and it sometimes hurts to have see , I also get shooting pains in my vagina sometimes ...
What do you guys think it is and what can I take to get rid of it? 
I can't go to the doctor because I'm on holiday in the UK and I don't have the money to see a doctor ..
