6 months pregnant, and my mom has shingles WHat do i do?

I am 6 months pregnant and on weds, 2 days ago, my mother found out that she has shingles. She lives in another state and was given the antiviral meds 3 x day for 7 days which she started on Weds. Here's the dilema. My baby shower is in 1 week and she will be here on Friday (in 7 days). Will she infect me or my guest at the shower? I've already had chicken pox and had the vaccine when i went into the military. I also have 3 other pregnant women coming that also have had chicken pox. I say my mom is fine as long and she doesn't touch anyone if she has open blisters. Am I wrong? Or is being in the same room with her bad? She has to actually touch someone with an open blister to expose someone right? I don't want her to not come to my shower.
