Does this look like implantation bleeding?

Had my last period 4th May till 10th May

My cycle is a 35 day

Had intercourse quite a lot last month, not sure what my fertile day was as the calculator came up with loads of calculations.

Says my period is meant to be due today, but for last two days had had this pinkish tinge discharge.

Does this look like implantation bleeding?

Sorry for the TMI
