I came off my pill in July and had my first period in sept and they’ve been regular ever since. 26 day cycles. Since coming off my pill I spot for a few days before af starts. My period was due Friday and I started spotting weds so assumed af was on her way. But I’ve only had spotting for 4 days and nothing else. Now it seems to be stopping. No bright red blood, just brown, sometimes pinky. I’ve done a PT and it’s negstive so I’m pretty confused 
What could this mean?
