Help please

Does this look like old blood and uterin lining? I’m on the pill and my boyfriend always wears condoms and pulls out. I checked the condom after we had sex and I’m like 99.99% sure it was perfectly fine. We also had sex on the last day of my period which ended a week ago. I was checking my cm and this is what I got out of my vagina. Please tell me this isn’t implantation bleeding
