I Bought Some Probiotics Even Though I Was Fine But

I bought some probiotics even though I was fine but thought it would help my "fuzzy thinking" (according to the advertisement) and thought it would be safe. I took them for about 3 weeks and stopped because I was feeling a "tingling" feeling in my body and thought it was from these probiotics. Now, about 1 - 1/2 months later I have a yellow tongue in the back of my throat and less appetite. I'm worried I screwed up my bacteria in my body with those silly probiotic pills. Is this the cause of my tongue and lack of appetite?
