Itchy feet

Hi everyone! Lately my feet have been itchy when I take my shoes off at the end of the day or get in bed at night. I thought it was a combination of hot/humid weather in Chicago, swollen feet, shoes that don't really fit anymore, and my feet being dry in general. But then last night I let Google get the best of me. When I googled itchy feet and pregnancy, Cholestasis came up. I'm pretty freaked out and am thinking about calling my doctor tomorrow. From what I've read I think it typically happens closer to the end of pregnancy and I'm only 23 weeks now. I'm just wondering if anyone has any similar experiences. Thanks everyone!
