Shot in the dark?

Tried posting in general TTC group but no response. So I figured I'd post in here. So Feb 2nd I got my positive ovulation test, well for some reason since the 4th of February my boobs have been sore. Then today the 5th of Feb I've been cramping. I never have sore boobs or cramping unless my period is coming that day. I'm not sure what to make of how I'm feeling! Could it be implantation already? Or maybe my body's already showing pregnancy symptoms? I'm so unsure! Any advice would be wonderful as I'm really hoping this is my month!!
