Is this eczema or something more serious? - eczema. more condition_symptoms

I have a small rash in the upper body is a bit like eczema, but never in my life. I am 11 weeks pregnant and have a little bit worried. Is it worse to do something only in relation to pregnancy or, even better? I'm going to my doctor next week, but all information that could be made before hand to calm down a little.
