Anyone feeling uncomfortable in their pregnancy body?

So........ I am so happy I'm finally pregnant with a healthy baby!  But..... I feel really uncomfortable in my own skin.  I am a Personal Trainer who's use to being in top condition but can't seem to find the energy or will to train.  This in return is making me feel uncomfortable in my own skin.  I've never been overweight or "soft" in areas and my boobs are huge!  Anyone else feel this way or is it only me?
