Std testing

Does anyone know where I can get std tested without insurance or money ? I’m overthinking that I have chlamydia . I know symptoms are silent but like my period keeps acting like it’s gonna start and i bleed a lot for a few hours but now it just stopped . And it’s like old blood now . Or I’m scared I have something else . And I already have anxiety so I’m overthinking it but I just need to know where I can get it for free and get treatment for free if i do have it because I don’t have insurance or money at all . And I’m terrified . I know about planned parenthood but I saw that there might be a $30 charge fee . Also I didn’t know what topic to put this in so I put it in this one .
