my last period was march 25, missed my period in april and have been cramping. I am now starting to spot very little but it is light pink. What could this mean? could i be pregnant or what is the deal? had bad cramps that whole month like my period was around the corner but it never came. I took HPT they were negative. Now i am spotting light pink color when i wipe and the cramping still remains. could i be pregnant?
