Mid back pain

Vanessa • I am 37 years of age, happily married with 2 big girls. My oldest is 15 and my youngest is about to be 13. Pregnant with my rainbow baby boy #3, so excited n loving every minute of it!!!

So im 34 wks n 3 days, usually I have lower back pain. But the past week I've been having pain in my back around the bra area. Hurts pretty bad n not used to it, plus can't get comfortable at all. What may cause tht pain in tht area?
