Ovulation or implantation

So my af was 2 weeks ago & now i am in my fertile week day 14 from Saturday & ends this Thursday but I think I ovulated right after my period ended & i am having very very light pink spotting only when I wipe but it wasn’t there this morning, my fiancé & I did bd over the weekend like a lot & we used pre seed, but isn’t it too early for anything to happen. ? I’m just confused if it could be early implantation bleeding or just old blood maybe ? If u guys need a pic i will post one .
