Pregnancy eczema?

Ch

The entire month of January I’ve been dealing with what my doctor says is eczema behind me ear. Skin keeps crusting and cracking, healing, and cracking again. For a week it even got infected from all the cracked skin. He prescribed me an antibiotic and cortisone cream which he and told me repeatedly was safe in pregnancy, but it just stresses me out having to use it! Obviously I want to avoid it getting infected again, but what the hell? Anyone else dealing with weird skin stuff?
