Itchy ?

Ok tmi and I’m apologize . But since about 2 days ago , down there has been itchy and a little uncomfortable . I go to the Gyno the 18th , but I just wanna know opinions of what you guys think . I don’t think it’s an std because I haven’t had sex in over 2 months & I really haven’t changed up anything down there , I wear cotton underwear and don’t use soap down there .
