Could I be pregnant?

Angela

First pic shows when I ovulated. I’m 12 days late for my period. I took a test at 2 days late. It said negative. A week before my period was due, I had light spotting. It was light red/pink at first then turned brownish. I urinate more frequently, increased appetite, feel nauseous without vomiting, and have sore breasts. I plan on taking another tests just wanted some insight. Thanks:)
