Very bad back pain!

I'm having very bad back pains! I'm 27 weeks and 4 days pregnant I've been like this through out my whole pregnancy but I feel like it's getting worse specially when I try to walk! Is there any way I can get rid of it or try to do something for it to go down a bit I turned to the side when I was laying down and it felt like my back was going to break I was in tears! That's how bad it hurts! 😔 please help!
