Obstetric cholestasis

I need help and support :-(
I'm 26 weeks pregnant and went to the Labour Ward 3 weeks ago with itching. My bile acid levels came back at 63, last week they were down to 22 but this week they've jumped up to 215! 
I'm so scared that my little boy won't make it. 
I've been referred to a specialist and she has upped my dose of URSO to 3000mg daily. I have more appointments next week to see if it's gone down slightly.
Has anyone else got experience with this? We're your BA levels also this high? Was your baby OK? 
I'm petrified and can't stop thinking the worst.
