I have white discharge with odor and yellowish. They are also thick and flow in abundance.

A neutral soap like Allenbury would be good or a goat's milk soap like Caprina.

If you have a fishy odor, you may have a bacterial infection and should see a doctor for antibacterial treatment. If there is no strong odor then it is quite possible that it is a fungal infection which can be treated with Canesten.
