I am getting sooooo out of breath doing the smallest of tasks and it is really worrying me. I am only 6 weeks but I feel as if I am 38 weeks pregnant! I can't even run a bath without getting lightheaded and out of breath. Is this normal? I am getting a little bit worried on how easily I am out of breath so early on in pregnancy! Even walking upstairs slowly kills me. I am not overweight and relatively healthy.
