Bleeding on CD18- ovulation bleeding??

So last month my period was 7 days late, which has never happened. It was 7 days long and heavy like normal. I’m now on CD18 and yesterday I started having pink discharge. It’s only when I wipe, not even enough to get on a pad. But it’s still been there all day today, ranging from red to very light pink but again only when I wipe and only as much as what’s shown in the pic. We BD today just incase it’s ovulation bleeding, even though per the app I should have ovulated on CD 15. Anyone have suggestions??? I’ve never had ovulation bleeding before. And there no way it could be implantation bleeding as we have the BD since I started my last period.
