Heat rash / pregnancy rash/ eczema. having it currently, just manage diet.. but it won't go away till after give birth some time also la. I use smoothie woothie spray from inara.organics to calm it daily. Best not to use steroids.
I had very bad rash at the leg when I was pregnant. I didn’t really do anything about it though… it disappeared after I gave birth. Not sure if it was hormone changes. You can ask your gynae.
