Spotting or period after pill?

Hi all,

I came off the pill and had the withdrawal bleed but then nothing til AF 6 weeks after.

Then 4 weeks later I had what I assume was AF.

But 2 weeks since then I’m now experiencing bleeding but not sure if it’s early AF, spotting or something else?! Tried opk and got positive throughout the bleeding so don’t think it can be AF - or is it? Anyone else get something like this??
