Excruciating pain question PLEASE help

I’m 38+2 and my hips are KILLING me to the point where if I have to walk even two feet I’m almost in tears. I seriously have a very high pain tolerance so this is crazy for me. I can’t even stand anymore and this has been going on for two days now... I’m 3cm dialated and 75 % effaced, is this a sign of labor? I literally can’t do this anymore, I can’t handle this pain.
