Period ? after pregnancy (pg, baby, breastfeeding ment)

Asher is now 5 months old.  He refused to breastfeed anymore after
March.  We were supplementing with formula because he wasn't gaining
enough on my breast milk.  (doctor's orders) I still haven't had a
period yet. (i was irregular before anyways) but last April (2007) i
had a period on my own which after that i got pregnant with Asher.
Now it's 5 months after his birth and i haven't breastfed since March
and today it's June 12 and last night i wiped after peeing and on the
tissue it was pink.  Everytime i wipe now after peeing it's light pink
on toliet paper but no real "flow" has begun.  What is going on??? Do
i count this as a light period or what???
