I’m six months pregnant and today while standing in line paying for my things at the store I had to step out because I started feeling really light headed, my ears started ringing and I was suddenly super hot. This has happened a couple other times, but I was always at home before. I seriously thought I was going to pass out but I took off my face mask, sat on the ground and drank cold water until I felt I could get up again. Should I be worried? I’ve told my doctor the other times this has happened and she seemed to think it was pretty normal as long as it isn’t happening all the time.
