Could it be from rolling your shoulders forward to deal with the extra weight in your boobs? I have this all the time and it's gotten worse since being pregnant. Try rolling your shoulders back and see if that helps.
I'm only 5 weeks and the back pain has really been uncomfortable the last couple of days. I went to my OB a couple weeks before I got pregnant and she said I have a tilted uterus that could cause back pain during my period. I figure it makes sense that I would feel it now too. Still, I can't stop worrying about it being a precursor to miscarriage.

Hope it gets better soon for you!
