Over did it today !! went consignment shopping and then went to burlingtons to find bins for my sons toys and as I'm waiting in the HUGE line my mouth starts to get watery and the room starts spinning!! Does this mean I was having a heat stroke ? Any ideas ??!! I'm worried ! I'm home now in AC and feel better but my baby is kicking reallllllyyyyy hard now...
