Implantation bleeding or something else

So my last period I thought it was my first day it was like 5 am and the blood was clear and a little blood which was pink and then the rest of the day it was no blood . The next day i started bleeding like regular but the whole time it was light pink and then the next day it was the same thing . For the rest of my period I wasn’t bleeding just spotting light pink and I bleed for seven days normally, so can anyone tell me what this is
