Uncommon Symptom

So this is a little odd, but I've been itching my feet like crazy the past week. It's spread to my legs, and it keeps me up its so itchy. My boyfriend yells at me all the time to stop itching because he thinks I'm going to rip in into my skin. I've been itching like crazy today so the heck of it I looked it up to see if it was a possible symptom of pregnancy. I read about "intrahepatic cholestasis " and now I'm worrying and probably over worrying. Has anyone experienced this symptom or any advice??
