Can a yeast infection cause pain in the lower abdomen? EDIT: STD?

It's been a long time since I've had a yeast infection and I honestly don't remember what it's like.

I'm crazy itchy and everything down there hurts. My lower abdomen hurts on both sides and is slightly radiating towards my back.

I'm also having a lot of discharge. It started yesterday and I was a bit scared that maybe it's PID. But I don't hurt as much today.

Have any of you ladies had pain in the lower abdomen during a yeast infection? I'm just looking for insight on what to say when I call my doctor tomorrow.

Thanks, ladies!

Edit:

It's not painful when I urinate. But I feel like I got punched hard in the vagina.

Oh my god.... I caught my fiance cheating yesterday... Could this be an STD?

Fuck.
