Implantation Bleeding or AF after my miscarriage?

Jorden

Hello!

I miscarried naturally on January 26th at 7weeks. Levels returned to normal February 8th. My husband and I haven't been preventing pregnancy since I miscarried. I've had cramping for about a week now, headaches off and on, and on Wednesday I began spotting a brown discharge. Nothing heavy and it's occurred off and on.

Could this be implantation or just a really light AF?
