Possible shingles? Any doctors?

Kyla
I am going to call my OB in the morning. It's very itchy and it's causing pain it's so itchy. It started as a rash this morning and now it's all blistered. I am pregnant. I saw pharmacist who said it looks like shingles. 
I work in a daycare. Not directly with kids but my office is in daycare. My boss hasn't said to not come in but is this possibly shingles? It's on my right neck only.
