Arm numbness 4 weeks

kayla

So I am four weeks pregnant. I randomly after my shower started to get tingling in my left hand and arm. I felt like my carotid was pulsating out of my neck - only on my left side. I looked in the mirror and it was visible. I am trying to stay calm but I want to freak out. The tingling stopped and not I just feel super weak near my left should and collar bone. I threw up a little too. Anyone else ever hear of this?!
