37 weeks with dual back pain

I’ve been having a lot of discomfort, and yesterday I started having back pain. Well the back pain today has gotten a lot worse! Dual and achy. I’ve been resting and drinking tons of water but it hasn’t gotten better.

This is my second pregnancy and my last was an emergency c section due to placenta abruption at 38 weeks. So I don’t know exactly what labor pains are like. Ive had lots of Braxton Hicks and pressure for the past week but the extreme back pain is new and is just not easing up.

Is this labor or is this still just my body getting ready?

I’m scheduled for a repeat C section on Dec 1.
