Tmi pain

So I didn't want to Google this because google is stupid and my next appointment is on the 15th. So I thought why not ask you ladies. So I have been having this pain for 3 days now and it starts right above the opening of my vagina lips, (omg so awkward, i dont know what else to call it lol) like it's just literally above where the lips start. And in my inner thighs And it hurts to the bone. Every time I stand up And try to walk it hurts really bad. And I can't lift my legs up to put on pants and stuff because it hurts. Do any of you ladies know what this is? or are experiencing the same thing. I'm also 39 weeks today, so is it like a sign of labor?
