So much pain

I have such persistent DULL back pain. It started a few hours ago. No contractions that I notice but the dull pain radiates into my butt low into my stomach.

I’ve had a heating pad switching from my back to my under my belly.... and took some Tylenol..

I really don’t want to be in labor (which I know I have no control over) cause our induction is set for my husbands birthday haha... but also I’m 38.5weeks and I’m sick of being pregnant so though I’d be sad not to have him on my husbands birthday I would just be happy to have our boy in our arms.

Last I knew I was 1.5 cm dilated, still pretty thick and anterior and super soft....

Any tips on getting relief from back pain?
