Implantation Spotting or Period

Hey guys, so I had my last period March 14, and I started brown around April 3, which should be 3dpo according to the picture. It is now April 10, and I am still spotting but now it’s like a light red and a slight orange/ pink color. Could this implantation spotting.

Side Note; it’s on and off some days I barely even spot. But I wear a panty liner just Incase, but I never spot so much to where it’s like a period flow.

Thanks in advance!
