itchy vagina, small bumps

so i have a boyfriend and we’ve had sex once without a condom about a month and a half ago. i’ve never had sex with anyone else and neither has he, but he has engaged in oral sex with about 7 other people. about two days ago i noticed that my vagina (inside my labia) was really itchy. the itchiness usually isn’t too much of a bother, but it’s comes and goes. i also noticed a strong fishy smell for about 2 days before my period, then it went away. i had been using summers <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> wipes a lot in the past few weeks and had been using the wrong absorbency tampon for a day (super plus absorbency when i had a light - medium flow). I took a look inside and i notice a tiny patch of little bumps that were the same color as the rest of my vagina. the didn’t really hurt too much to touch, but they’re tightly packed, almost like broccoli. does anybody know what this could be? i’ve gotten the HPV vaccine. i’m not sure if it’s a yeast infection from the tampons/wipes or an STI or what, but i’m freaking out. please help me!!!!!!
