Itchy body 19 weeks!

So I have been experiencing itching the past 4 days. During the day I don’t really feel itchy at all. It’s mainly been at night when I’m sleeping. The level of itchiness isn’t overwhelming either just annoying. It’s not on my hands or feet at all. I called my doctor and am getting blood work done to check for Cholestasis but I’m so scared! I feel like it would be so early to have Cholestasis. I broke down crying because I’m scared for my baby! I’m happy The are checking everything tomorrow though. Part of me has a great feeling that it’s not but knowing my luck...who knows.
