Strong like vaginal discharge.

I had a mixed infection of excessive vaginal discharge which was whitish gray in colour and only once or twice looked yellowish green and with pain before and after urination and itchiness, i was told it was mixed infection and could've been from sexual activity or hygiene the last time i was sexually active was a month ago and was protected sex. Before that i had unprotected sex with only one person and that's when i started having this infection. I had left it untreated for about 5-6 months. So the last week i went to the gynac and she asked me to use cansoft cl and triben cream, i used that as per the prescription and I've been off those meds for About 3-4 days now but my infection has not gone and my Vaginal discharge is still milky white but it's first watery once discharged and then becomes string like once dry. What is the infection? How can I make it completely go away cause I'm tired of having it. I haven't been sexually active for a month.
