Crazy cramping 9 DPO

Janna • Expecting baby #1 December 2014!!
Hey ladies, so I was literally woken up in the middle of last night (morning before 9 DPO) because I had such intense cramping. Felt like AF cramps but almost more intense and less painful? Not sure if that makes sense. Anyways, still slightly feeling it now (930 am here), but no AF, and not due til Thursday (I have a short luteal phase). I'm hoping it's implantation cramping but trying so hard not to get my hopes up. Any ideas? And I was planning on testing tomorrow, but would that be too soon? Thanks!!
