Implantation bleeding and cramping

Allie

Did any of you experience pain with implantation bleeding? I have had cramps the last few days but worse today. For the last few hours when I wipe its brown but none in my knickers. I'm not due AF for another 4 days. I'm pretty sure it's just the witch arriving early as feels like AF pains but didn't know if it was normal to get pain with IB or not?
