What's going onnnn?

Kayla
I had a normal 6 day long period... But I never cramped ( I usually cramp so badly) ,bled a lot less, lol and I didn't cry once. I even said i wish my period were alwas like that one. 6 days later, I had pink spotting. 2 days after that until today... So three days I've had a combination of brownish pinkish and now slightly reddish spotting. Why???? Should I see a doctor?
