I had my period for 3 days and then it stopped. It was light. Normal it is heavy and lasts 6 to 7 days. The next month, I had spotting for 3 days and then it stopped. I have taken 4 pregnancy tests and the all came back negative. Im having symptoms like tenderness in breats, nausa, headaches, lower back pain, irritablity, emotional. Can I be pregnant or is this all in my head?
