Implantation or period?

This was a photo from yesterday but not sure what to think as I still haven’t bled properly at all intact I’ve had only 3 little spots of colour today ....

Ye

Yesterday was day 2 of my “period” But that was 4 days late, I didn’t get any clotting or actual bleeding but this seems too much for implantion bleeding maybe ?? I honestly don’t know ...

I had a chemical pregnancy last month so maybe that has something to do with it ? Can anyone give me any insite in to weather I should retest?

I tested before it started and they were all negitive so I really don’t want to waste more sets if I’m just being obsessive ?
