Eczema and Pregnancy !?

So I’ve had eczema since I was a kid and throughout my life it comes and goes patches pops up in super embarrassing places! One time in between my breast! My armpit(stated as an allergic reaction to the deodorant I was using and finally cleared a year later) now that I’m expecting it’s on my Genital area 😭😭 I haven’t went to my first appointment yet that’s in a couple of weeks I just need to know is there anything that I can do now that’s safe for the baby I use fragrance free soaps already and sleep camando 😫 it’s getting bad! I don’t know what to do I put this Cocoa butter Vaseline on it and it made it worse I even took a Benadryl(not even knowing if it was safe to take or not ) to stop the pain/ itching IT DID NOT WORK!
