Swelling around my vagina

I’m 35 weeks with my first, is it normal for there to be swelling around my vagina, like the lips are super swollen? I haven’t had sex at all recently so I don’t know what’s causing it unless it’s normal? It’s so bad everything feels like it’s bruised down there. It hurts to walk or even move and use the bathroom. Also, I’m not swollen anywhere else.
