How can you get rid of fishy odor ?

So I think I have bv me & my bf have been having a lot of unprotected sex he cums in me most of the time. I told him about my ph being off lately but he just does not get it when I’m trying to not have sex he still wants to so I give in like a dummy 🙄 I’m bout to be so serious now & be like NO cause I want my vag to not smell! It’s been smelling very fishy & also have discharge I’m trying not to itch because I heard that just makes it worst. What could I do to make the smell go away ? I have no way to the doctors or anything I’m going thru a lot w my fam so they don’t really fuck with me rn so someone please tell me what I could do to fix this ASAP
