Need helpful advice.. Herpes? BV? Yeast infection?

hello i had a really bad itch like it was so bad i had to go grab some monistat 7 cause i thought it was a bad yeast infection after having sex with my bf ( p.s it was an fishy odor after) but it seem like it made the itch worse so i used vagisil anti itch cream when i put the monitsat on but anyway im still having a feeling of discomfort down there and i still have a slight itch.. i also have a bumpy feeling in my vagina (if that make sense) i need help identifying what this might be?
Symptoms- Cloudy pee, light headaches & itching
Please help and thank you for all advice.
