Hurts so damn bad I can't sleep

I have something going on in my vagina that hasn't allowed me to sleep in 2 days.

I'm about to freak the fuck out.

It itches and burns. I'm y weeks pregnant and it hurts so damn bad all I want to do is cry. There is yellow dry discharge and certain spots feel like they are bleeding or so swollen they could burst.

Can I go to the E.R. for this?
