AF confusion

JV
Hey ladies- I need insight. I was due to start my period this out Saturday, 2/13. I started spotting on Monday 2/15, but only that morning. Then nothing all day. Tuesday and today it's been an extremely light pink flow, only when I wipe and a little on the pad. Nothing like a normal period. Also I am always on time. All my tests are BFNs. I've also had nausea/vomiting in the afternoons, sore boobs, pinching in my ovary area, cramping and headaches/dizziness. Would you guys chalk it up to a strange period? Or do I still have a chance?
