Implantation spotting or sneaky AF

Mrs OKW • Wife 💍to Omar, mom to 3 👸, 1 🤴. With God all things are possible to them that believe!

I'm clueless 😭

Went to the bathroom, saw some blood and assumed it was AF, put on a pad. After I came back, it was all dark brown after wiping.

How long can this continue before I can rule it out as AF.

With my first child , I had dark spotting; she's 13.

This would be my 4th child and 1st with my new husband. I'm 39.
