Back pain

I have this very sharp and achey pain in the middle of my back, just below my shoulder blades. It kind of feels like I need my back cracked. I have also been having tolerable sharp like pains in my lower right abdomin. I'm sure it's nothing and just normal pregnancy but my mom went into back labor with me and has been talking my head off about it so that's al been running through my mind haha. I'm 28 weeks pregnant, didn't know if anyone had any suggestions on easing back pain or what it may be😊
