who got skin rashes during pregnancy..i'm 24 weeks and those thing are at my legs

me starting got the rashes since 4weeks of pregnancy until now dah 32weeks..doctor said because of dry skin.. mybe lepas bersalin can get back to normal.. early pregnancy dulu sampai makan ubat doktor bagi sebab tak tahan gatal sangat menggaru sampai tinggal parut.. now still gatal tapi tak extreme like early pregnancy.. just everyday make sure apply krim pelembab..
