Based on what you've described, it's likely to be infected with otrus, which can cause skin rashes and abnormal skinforms, of course. It can cause dryness, peeling and texture, especially if you're pregnant, getting treatment as soon as possible to prevent further complications.
Doctor, I've been experiencing a number of symptoms recently: red organs, dry skin, tanning, and abnormally visible rashes on the diaper area, and I'm worried about the potential problems of pregnancy.
