Hi, I had started my period 10 days late. And two days before I started I was cramping bad and my upper back was hurting me bad. When I started my period it was coming out light. I have my [eriod for 7days but this time I only had it for 3days... what does that mean can anyone help me plzzz

Is it that you could be pregnant? I would get a test. You could also see your family doctor. I had a light period for the first few months of my pregnancy.
