What is this?? Possible implantation??

Hey everyone! So on the morning of 6/10 I noticed very very light brown spotting when I wiped. I thought I was going to start my period, which I’m 8 days late for, but it never came. I never saw the spotting again all Monday, but now I just got up to pee and saw this in the toilet. When I wiped it was super light pink and very little streak. I don’t know if this is implantation bleeding because I had unprotected sex with my boyfriend on 5/26. I had just started birth control and that was my 6th day ever taking it and he came in me. Help!!!
