Hello Doc, I Am 16 Weeks Pregnant. From Last 12-15

Hello doc,
I am 16 weeks pregnant. From last 12-15 days i am suffering from severe itching which results in red patches or rashes. My doctor advised for lft and cbc in which my sgot was slightly higher and tlc was also more than higher range. The next day I had the same test from another lab and lft was absolutely normal...but tlc and cholestrol levels were high. My doctor
prescribed me udiliv 300 twice a day for 10 days and atarax for 5 days. But it didn't had any effect, after which she asked me to take allegra 120...but still the relief is temporary. I am worried about any side effects of these medicines on my baby. Please suggest what should I do because the itching is unbearable.

Thanks!!
