Is this an STD?????

Hi guys so I’m currently freaking out. I usually do self examinations and today I noticed that something looked a little different… I’m freaking out thinking about every possibility and there’s really nowhere to go. I don’t think it’s an ER case… I’m just really nervous

I found dark colored raised skin by my vaginal entry… it doesn’t hurt, there’s no odd odor, my boyfriend and I use condoms. I got tested about a year ago and everything came back negative and like I just wanna cry right now…. TMI but this is what it looks like..
