Sign labor might be coming??

I’ve had the worse pregnancy and now that I’ve reached 37 weeks I’m dying for it to be over so I can get some relief and finally hold my baby!

I know lower back pain is usually an indicator that labor might be coming soon.

I’ve had very bad back pain throughout the pregnancy but always in the middle/upper back, until today. All day I’ve been having what I would describe as period cramps but in my lower back?

I’ve had really bad cramps in my lower stomach for days but it’s the first time it’s actually painful in my lower back as well

I’m just wondering if this could be a sign labor might be coming soon or if anyone has felt similarity before they went into labor?
