As my "bump" is moving up and getting harder (I say this because I don't look pregnant, just chubbier) I've noticed it hard to take deep breaths. When my lungs expand, I feel like they are being compressed by my ribs or something. Kind of like when you run for a long time and get a cramp. I don't know if this is normal at all. I'm 14 weeks 5 days with my first child.
