Is this contact dermatitis, I need second opinion?

Female, 20, only take birth control, excellent medical history.

Rash started two weeks ago with small spot on stomach, spread to all of my stomach, and now it’s all over my stomach, breast, chest, back, and spreading to my arms and thighs. It is extremely itchy. Doctor said it was contact dermatitis and gave me steroids that were supposed to clear it up but it has made no change.
