Implantation or period?

Kaylee

So I was ten days late with no signs of starting my period. But on day 11 I started having a very light flow. No clots or anything. I’m now on day three of it and it’s seemed to slow down almost completely. It’s very light in color. My OB won’t see me until I’m estimated to be at about 8 weeks. I had a chemical pregnancy in October. And this doesn’t seem to be very similar to that. The cramping was intense and I’ve had none so far even though I’m lightly bleeding. Could this be the implantation stage or am I just having a really late period? My period is always on the dot with when it starts. I used to have the bar in my arm and got that taken out more than a year ago. Don’t know if that’s effecting my ability to get pregnant or what. These are my tests from the past three days. Top is most recent.
