Cholestasis diagnosed late?


I'm itchy at nights. I didn't think much of it, just the occasional Benadryl. It's not just hands and feet but more all over. And not raging it's mostly annoying. But now I'm reading about ICP and starting to freak out. I'm already 37 weeks, so waiting a week for blood tests seems pointless since I'm past the emergency delivery date. I'm terrified of still birth.

I already do NST and BPP every week now. Can they tell anything from that? I do the next ultrasound on Thursday.
