Skin infection

Might be pregnancy related rashes, try using pine tarsol it can help to relieve the symptoms and itchiness especially at night. Then night time can use prickly heat powder. The pine tarsol gel is available at Watsons / pharmacy. Mine started in third tri and went away after give birth. 5 weeks post partum I have it again. 😂

When your body go through a different hormone changes, you will encounter dry skin, red bumps, itchiness, etc. So nothing can be done for now. But, do ask if it will be gone after pregnancy or is it prolong red bumps, etc. And if there's any better skin lotion that helps you.

Could be eczema. I had similar rashes on my body when I was pregnant which never happened before. My gynae gave me steroid cream to apply which he said is safe for pregnancy. It went away after about 2 weeks.
