Suggest Treatment To Stop Constant Itching Since Pregnancy

hi there, iv been experiencing severe itching all over my body since about month 5 of my pregnancy, my daughter is now 8months old. Ive been prescribed creams and anti-histamines and had a blood test last week which came back as 'no action needed'. I have no visible rash or dry skin. Its really getting to me as its non-stop and has been going on for so long now! Could you shed any light as to what I can do?
