Help please

Okay so I am scared to go to the clinic because I’m nervous about the results I’m gonna have. And I just don’t want my parents to find out. I’m 19 years old. And I haven’t had sex in a minute so the whole uti and discharges and chlamydia stuff is new to me. But like idk if I have those three things cause I don’t feel the symptoms. I mean yeah it do smell down there and no it don’t hurt when I pee it just feel a lil warm when I pee. I just need some help with this.
