Mixed infection/sticky vaginal discharge

I've been having this problem for almost 5 months now. It just progressively got worse every month. The symptoms were almost common the last 4 months (white, milky excessive discharge which was watery but also string like in nature, chemicalized smell, itchiness and pain after urination), last time i was sexually active was a month ago (19th September) where i had protected sex, before that i wasn't sexually active for 2 months. To conclude i had a lot of unprotected sex during April-June with only one person. I went to the gynac like twice 2 & she had asked me to take fas 3 kit+clingen forte tablet for mixed infection but it only increased my symptoms to sticky string like vaginal discharge which is yellow-green in colour with a chemicalized smell and pain at the upper left of my vulva whenever i sit for long. The recent gynac visit had told me that i should use cansoft cl suppository and triben cream and consume bandy tablets for deworming. What infection is it? Will it get better?
