possible STI


I have this annoying itch on the top of my vigina where the hair is I thought it's because I'm using a new washing stuff for my clothes. but now my discharge starting to smell bad and there's more of it . I been having un-protected sex with my new boyfriend but he said he gets tested very reguly and when after he's had one night stands . but I'm worried I got a doctor's appointment this week but that's about getting the implant in my arm. did any one else get this problem
