Mild itching at 20 weeks/cholestasis?

For the last week or so I’ve been having what I would call mild itching spells (in my palms mostly) that feel like a deep itch that is hard to relieve. Usually it happens between 4pm-8pm and ends up going away by the time I go to sleep. Google led me to cholestasis and of course I’m super worried now. but the research I’ve done makes it seem like it doesn’t usually develop until later in pregnancy and the itching is intense and miserable. I’d love to hear from anyone who’s had cholestasis, how do symptoms usually start out and can it happen around 20 weeks? TIA
