I had a light red off and on bleeding for 2 days instead of my normal (heavy) period. I also have mild cramping in abdomen, lower backpain, dizziness, raging hormones, headache, lack of energy and fatigue. 4 days later I m experiencing light red spotting. I ve done 2 pregnancy tests and they ve both come up as negative. I ve seen a doctor who said to repeat the pregnancy test ina few days time but does not sound convinced that I could be pregnant.
