Possible cholestasis?!

Itching just started last night on my palms and fingers but no where else. Not having any of the other symptoms (jaundice, pale poop, or dark urine) and wondering if this is just a reaction to something or if it’s the real deal. I have an appt at 11:30 with my OB and am already monitored weekly by maternal fetal medicine for GD. Should I give it til Friday to see about it and mention it to my OB or call tomorrow to get testing done? Don’t want to jump to conclusions but I’m almost 34 weeks and I know in most cases they induce at 37 if you do have it. Thanks for all advice ladies. This isn’t even something my doctor has ever mentioned can happen so I’ve just been researching on my own.
