Hello, So I Thought I Hit Right With Days That

Hello, so I thought I hit right with days that I was ovulating and I was cramping all month long and I felt different. So I thought I was pregnant. Took a test. Negative. So Christmas Eve day is here and I think I started. So the bleeding went from light to mild then brown and stopped after a 2 days and now hardly anything. Take a test. Negative again. Could I still be pregnant?
