Rash on neck and face

So I have come up with the rash in my face and neck and some other symptoms. Now I think it’s ether rubella or shingles.

I don’t want to bother the hospital because I know they are busy and when I go there I feel like I’m taking up there time.

But I also don’t went to not go and become worse

My doctor is closed for the weekend until Tuesday. (She’s in hokiday) then I see her Thursday anyway.

Should I wait and talk to her about it the. And see if it gets better or do I go to the hospital tomorrow?
