Cholostasis while pregnant

ATM

I'm almost 31 weeks and for the last 3 or so weeks my lower legs have been annoyingly itchy. Thought it was razor burn but no rash or bumps are present. I have continued to itch without shaving them again. It's more so my lower left leg to my ankle. Happens more often at night. It feels like the intense itch of a mosquito bite or walking on the beach with freshly shaved legs. Occasionally I'll itch on my left hand or right foot. I have an appointment monday so I'll mention it but is anyone going through this too?? Been diagnosed?
