Severe Back Pain... Anyone else?

Kayla
So I'm 35+3 weeks pregnant. My entire pregnancy I've had Braxton Hicks contractions pretty bad. However I haven't had any type of severe back pain. Last night I went to get ready for bed. While brushing my teeth I literally almost threw up at the severe cramp that went through my back. It was out of no where. Had to call my SO to have him help me to the bed bc I literally couldn't move by myself it hurt so bad. I finally was able to lay down. I was up the majority of the night in pain and it is still going on today.. I've had cramping in my belly as well. I honestly don't know if this is Braxton Hicks still or if it's the start of the real deal. Either way... ouch! It hurts! I apologize for the long post!
