Back Labor

Brandi • Married 💍 Boy mom ×4💙💙💙 & Expecting 👣
I just turned 37 weeks and I woke up this morning with a little ache in my lower back... it's gotten a little more noticeable within two hours. Could I be having signs that labor is starting ? Also, if I am having contractions in my back will the pain come and go or is it consistent?
