Pelvic pains?

I have been feeling weird little throbs in both of my pelvic sides (left and right) in place of the AF like cramps I'd normally feel. It comes and goes but it's on both sides and I've never expierienced it before!!! I'm anywhere between 10-13dpo and I feel different if that makes sense? Anybody have weird sensations in their pelvic areas in early pregnancy? Or before AF for some strange reason?
