AF or Implantation?

Megan • Mama to our little rainbow-Finley James
Woke up today with a tiny bit of bleeding.  I'm really hoping it's not AF showing her ugly little self early this month.  I had implantation bleeding last time at 10DPO and got my BFP at 12DPO so I'm trying to stay hopeful.  I'm 11DPO right now though and feeling a couple twinges of cramps so I'm thinking I might be out.  Damnit!
