Intrahepatic cholestasis of pregnancy (ICP)

Has anyone in here have this? I think I may but I’m not too sure I’m 35+1 week and I thought I had this stretch mark that was itching and burning. I asked my doctor about it Tuesday she said it’s actually a blood vessel like older people get on their legs. And if the itchiness get worse she’ll have to deliver the baby. Well idk how to tell if the itchiness gets too bad. It’s starting to burn with touching it. I want to try and wait until next Tuesday to see my doctor but my tummy seems like it’s getting worse. Idk if this is the same as icp or not.
