Have been experiencing this for a few days. It is normal but it stresses my husband out to no end.
I'm the same way. After walking around or doing something I'll take a huge breath and my hubby keeps asking "are you ok" but its just because I'm trying to catch my breath lol
Unfortunately its just another pregnancy symptom and its because the baby is pushing against your lungs and just gets worse as baby grows..I feel your pain.I climb of stairs and feel soo out of shape
