Implantation Cramping??

My period isn't due until 1/30 and I'm experiencing cramps that flop between my lower abd and lower back. This feels very similar to menstrual cramps, it's keeping me awake. Is this the right time period for implantation cramps?? I don't usually get cramps until the day of or before my period. I've also had very watery cervical mucus, with a milky white color to it. I really just hope so...
