Hey!
I am the same, had eczema really bad as a child and now has flared up quite bad since I found out I was pregnant. I am using a chemist brand cream that they made up behind the counter, and have just been prescribed Diprizone (spelling?) and my Dr says it is very safe to have while pregnant. In the past I have used Diprizone and it works really fast and doesn't sting when you put it on like some creams out there.

Hope your eczema gets better!
