Being that my period trackers gave the dates of Aug 5th, August 7th, and August 10th, could I be experiencing implantation? On the 7th (one of my ovulation days), I had major cramping and pain on my right side. It lasted until mid day Saturday. All this week I've been feeling mild pulling and mild cramping, been overly exhausted, and not feeling like myself. I'm trying to not get my hopes up but could this be a sign? My last pregnancy was in 2009 so I barely remember the signs I had.
