Back pain?

Mattison • I am 18 and due with my first baby may 18!! <3 can't wait!! 😍😍
I'm a little over 17 weeks and i have severe back pain on my right side. It's my entire right side of my back and it hurts whenever I lay down no matter what position. It's starting to really affect my sleep and making me nervous. Going to the docter soon but I wanna know if anyone else experienced this. Thanks for your help! :) any and all is apprecitated!
