I’m 38w3d pregnant and the past few days I’ve been getting dizzy out of nowhere. Yesterday I went on a 2 hr drive to see my grandpa (I was the passenger, my bf drove) and when I got out of the car and went inside all of a sudden I got very dizzy and disoriented and then a couple times while i was there it happened again but went away after a minute or two. Today at work I was just walking around and all of a sudden I got so dizzy I almost fell down. I’ve had a very healthy pregnancy so far. Is this anything to be worried about or is it normal?
