37 weeks major Cramping! !??

I'm 37 weeks pregnant! I actually have Uterus Didelphys! A condition where I have two uteruses, 2 cervixes, and two vagina openings! Anyways most girls with my condition barely make it past 34 weeks. I'm at 37 with no complications yet! Although I've been having really bad Period Type Cramping! And I feel like my Ligaments in my stomach are tearing. . Is any of this a sign of labor? ? Please let me kno if you experience the same!
