My LMP was on 18th May 2007 and I was due on 12th June. Usually my period is very regular. But on 12th I didn't have any symptoms. On 13th and 14th I had few spots of pinkish discharge. And on 15th I started bleeding. 1 week before my period was due, I had breast soreness and fatigue. Now the bleeding is accompanied by abdomen cramps (mostly on the left side), back ache, head aches and tiredness. What does this mean?
