help! implantation or miscarriage?

Hi I need some advice and help. 
Today I started what seemed like my period -4 whole days early I add and I'm very regular! - but tmi when I wipe the blood is pinkish and has purple in it too. Like a hint of purple. It's coming in clots also and I'm not sure what it is.  It also hurts when I wipe, so if anyone has gone through this please help!
