extreme pelvic pressure

Koi
no for real... when I say extreme I mean EXTREME. 
The pelvic pain has been happening throughout the third trimester but mostly while I was walking. Now that the baby has dropped low, I could be just sitting down and my pelvis will start radiating with intense pain and pressure. It's been like this for the last 3 days. 
I am 40+1 now, so past my due date. I'm looking for a glimmer of hope that labor could start as soon as today!
Anyone else out there feeling this/went into labor as a result?
