skin ichiness

I'm now in 34 weeks pregnancy , and my toes and fingers started be very itchy since 1week ago .. now slowly it spread to my whole body .. it feel really itchy especially during night time .. I check from Google and it shown might have possibility to happen ICP ( intrahepatic choletasis of pregnancy ) . I took & applied the medicine which doctor gave to me 1 week ago but it doesn't work to me .I applied aloe vera extract too . Still the same . Anyone experience the same problem with me ? What can I do?
