Not TTC just paranoid help!?!? ?

My last period was December 27th through December 31st and according to my ovulation calendar if the start of my last period was December 27 th then I am fertile (ovulating) January 6th through January 11th..... Today's the 3rd and I feel little twinge feelings in my abdomen and soreness kind of. I haven't had any ual relations since September when I had a pregnancy scare.... and I took 7 home pregnancy tests throughout October all negative and I had a blood pregnancy test on November 3rd it was negative too. Am I feeling early ovulation or what????????
