Last Wednesday I Noticed That My Vagina Hurt When I

Last Wednesday I noticed that my vagina hurt when I started peeing. I assumed it was a ingrown hair. Now still happening, it also hurts when I wipe. I started my period and it feels like something is blocking my tampon from going in, so I looked and I have a couple big red bumps, I haven't had sex recently so I don't understand what it could be.
