Anyone diagnosed with ICP in first trimester?

I'm 10 weeks pregnant and for the last two days I've noticed my skin has been particularly itchy and more in the evening. I quite often have allergic reaction so initially thought it was that but as I don't have a rash it can't be that. I itch everywhere and it's not really palms or soles. I have all day nausea and heartburn in the evening. No dark urine or pale stools. I am going to go to the Doctors on Monday for blood test but though I'd see if anyone could offer advice on here too. I'm worried that I have it. Can it be medicated?
