Yeast infection or just irritated?

Tuesday night I had unprotected sex took a shower and while in the shower I saw summers eve and have never tried it so I went ahead and used some thinking it would help me get a little cleaner after earlier activities. So I'm pretty sure I washed the wrong place with the soap and 5 minutes after my shower I started getting uncomfortable down there and the next morning I was itchy so I tried using wipes to wipe the area to make sure it was clean which was not a good idea cause then I had to go to work with it swollen and the itching was worse. So I got home looked up some stuff and decided to try a acv bath it soothed it over night and part of the morning and then it went back to itching and being sore ...before the acv I had no smell and no unusual discharge but now I have a faint smell not fishy but idk what to call it though its not a bad smell and when I wipe it was like brown stuff like it was dirty and after I wiped and used the restroom it actually became a little less uncomfortable... WHAT ON EARTH IS HAPPENING?

UPDATE:

I tried acv baths for 2 days and it seemed to relieve the symptoms for the most part. But now that the symptoms have eased up I now have a yellowish brown discharge and it's freaking me out. I bought the "Queen V: the eraser yeast infection relief...should I try it or because I don't know what it is just wait?
