Back pains

Jamilla • I have two sons, ages 4 and 5, and pregnant with my last baby which is a girl finally!!! Due August 26
I am 25 weeks and 4 days and last night I had the absolute WORST back pain ever! It felt like my muscles were contracting and it had me in tears. I could barely walk. My question is, is it possible that I was experiencing back labor? Should I call my doctor?
