Braxton hicks help!!

I'm 37+3 and for the past hour or so I've been having the worst Braxton hicks. I've been trying to sit/lay every which way and this terrible cramping/back pain will not go away. This is the worst pain I've experienced so far this pregnancy, I know I'm not in labor but these Braxton hicks get worse and worse every day I just hope this little boy comes out soon 😔 Any tips on how to relieve them? I've been hunched over a pillow on my hands and knees crying just wishing this would go away.
