implantation question

Kathie • Im a mother pf two, 12, son and 10, daughter. I was pregnant in October and had a MC in January. This is my 2nd active month hoping for a healthy pregnancy!

what's the time period you can have implantation bleeding? I woke up this morning with bleeding just when I wiped, I'm also having slight cramping. I'm pretty sure I'm out this month. AF is due on Wednesday.
