41 weeks pregnant, extreme pelvic pain. :(?

Im 41 weeks and i have recently had pretty bad pelvic pain when i move, like walk or lift my legs or sit up. But then just like the past 3 days it has been hurting soooooo bad, almost unbearable to walk. Im kinda wondering what this could be (besides the obvious, baby moving down and pressure) but could labor be soon. I had a membrane sweep a week ago, and if i dont have her in a week ima have to be induced, and i severely dont wanna be induced. Anyhooo if you have had this happen to you id appreciate it if you shared your experiance. Thanks much xx
