I have back pain. It's mainly in one side. My right. I'm not even 13w yet and I'm only really visibly pregnant at night with a huge bloat but my back is killing me this morning. It's aching and even after doing some stretching I feel wiped out by the pain. Isn't it too early for me to have back pain? It's sort of mid way up my back on the right side. Worrying me. Anyone else had early back pain?
