32+5 can't sleep: itchy hands and feet!

Danielle • Married my best friend on 4/11/2015. I have a son—rainbow baby born 2016, and trying to grow our little family💗💗💗
It's 4:45 am and I woke up about an hour ago unable to sleep because of babys hiccups but then slowly my feet and hands started itching. I thought it was nothing until about ten minutes ago, I started researching on the Internet to see if this is normal. Now I'm terrified I have obstetric cholestasis. Any ideas? I'm I crazy or should I be worried?
