Itchiness

Alright so I posted something yesterday about having an itch. I don’t think it’s a yeast infection because I don’t have any other symptoms the white discharge went away... I think it may be an allergic reaction to the new soap I got... because I have really sensitive skin and the itch/irritation came a day or two after my first use of the body wash. Could that be a cause or am I just oblivious?
