My head is SOOO ITCHY!!!

Hi ladies. My scalp started getting itchy around 2-3 weeks ago(I am 31 weeks) on my scalp. I thought it was lice because I’ve had it before and it sucked, but I didn’t find anything in my hair! I’m also itchy on my neck and shoulders area. My arms and legs get itchy occasionally. Ordered my blood test already to check if it’s possibly cholestasis.. Has anyone experienced cholestasis in these areas?

Just for background, my hair is really curly and on the dry side. I don’t wash my hair every day because my natural oils don’t build up quickly. But I haven’t changed my routine anytime recently..
