Strange Early Pregnancy Symptom?

Sienna

I am currently in my 4th week of pregnancy and over the past few days I have had a super weird symptom that I never had with my two daughters. Every night I have hardly gotten any sleep because I am SO freakin itchy. Some nights it is my arms and last night it was my ankles. Literally a constant intense itch all night long. Has anyone else had this?? It is so bizarre and annoying!
