chicken pox or allergic reaction need advice

It's basically everywhere. Just kind of appeared. The red mark on her stomach isn't a scratch it just appeared as well along with another one on her chest area: what is this??? 
*Yes I'm going to consult with my ped, I just wanted other insights on people who have dealt with this. This just happened minutes  before I posted this, and i get answers quicker on here 🙂 Thanks for the replies!
