Since last week I noticed my shortness of breath and this week my hands swelling. I'm going into my 24th week and since my 16th week, my doctor has asked me if I noticed any swelling. I'm never short of breath, or rather, never was prior to becoming pregnant. I run about two miles a day when I'm not pregnant. Lately though, it seems just the smallest of things I do can get me trying to catch my breath. Nothing to the point that I feel dizzy or lightheaded, but that I need to slow down some. My fingers are the only bit swollen as of now. I noticed it one morning after my rings felt as if they were cutting off circulation to my fingers. And hoo boy, were they a pain to get off!
During the day my hands and fingers are fine. It seems only at night they swell up. If you are worried about your swelling or shortness of breath, give your doctor a call. Hope I helped some in letting you know you aren't the only one in this boat.
