Recently I have been itching all over my body. I've tried creams my dr recommended and nothing helps. I am 38 weeks + 5 days and I went to the hospital for not feeling well. They ran a bile salt test but won't have the results till Monday. I looked up the risk factors and now I'm scared to death to lose my baby. Has anyone ever had this or dealt with this and how do they prevent anything happening?
