Yeast infections

So I had a yeast infection for the first time around June and ever since, my body doesn't feel the same. I notice every smell and texture and anything that isn't normal for me. I feel uncomfortable like I'm gonna get it again even wearing anything other then cotton granny panties. I can't get back to normal and now I feel like I have it again. How am I supposed to notice the difference between normal vagina stuff and the infections? I have very low key symptoms, the extra weird discharge which I feel coming out constantly almost like when you're on your period and you feel your body push it out and a weird smell and a little itchiness. I have the medicine I took last time but I won't know when to take it until it gets to the worst point. Any advice?
