Could I be pregnant or ovulating?

I had the mirena iud taken out on april 30th 2010 and got my 1st period 3 days later on may 3rd. I had a normal period I guess abt 4 days. Last night on the 11th my little girl kicked me when she was playing in my stomach and it got me cramping and then a few hours later my husband and I had . I knw its only been 8days since I started and I know everyones diff...I wldnt think I wld even ovulate yet but today when i woke up I'm have a very light color pinkish blood/liquid. What could this mean?
