Itching like crazy!

Michelle
Every part of my body itches like crazy, from my scalp to my toes. I thought it was allergies but nothing else is bothering me. I'm 16 weeks today, any ideas for a solution? Anyone else going through this? I haven't changed detergents or anything like that...same shampoo and body wash as always. Started taking Claritin each day, helped my nose but not the itching. I'm going insane.
