Hi, i'm very confused? My period normal comes on the 3rd of each month, but this month I don't know if this is my period or not. why I say that is because it came on the 1st of the month, it was light and had a brownish color to it. I was cramping so bad, I had lower back pain and also bloated. The next 2 days it was light but it was a red color, I was cramping again and had back pain. The next day (last day) it was light and it went back to the brownish color. Normal I bleed heavy on my first day to my 3rd day. Not This month I was Light and It stay on for 4 1/2 days. Please Help Me ? Could I be Pregnant?
