Anyone else?

I'm only 15weeks 2days and whenever I do something I get sooooo out of breath. My dad called today and even walking over to my fone from the kitchen to bedroom I was so out of breath my dad asked me why I was out of breath lol. I really find it hard to breathe properly at times. Is anyone else suffering from this or is it too early for this yet? Should I see my doctor about it? I don't remember this with my daughter and I worked full time until 34weeks on my feet all day up and down stairs at work.
