Implantation Question

Lynzee • Mommy to Ammarie, born on March 3,2016!

I am 7 DPO. When I was o vulating, my right side tended to cramp some. Well now my right side feels a little uncomfortable. I wouldn't call it cramping, I can just feel a little twinge every now and then. Im not sure how to explain it.

Could this be implantation? There was also a drop in my bbt this morning.
