shortness of breath

Amy
Hi,
I am seven weeks pregnant and I feel short of breath or as if I am trying to catch my breath. I don't have any other crazy symptoms but I am going to go tomorrow to get checked out. I work out and now I can't even work out for 15 minutes or go up two flights of stairs. Very weird for me!  Anyone else experience this so early in pregnancy? I am going for sono tomorrow to check everything. TIA 😄
