implantion bleeding or period

Amelia

okay so i had unprotected sex on may 1st and he told me he thinks he didn’t pull out in time and 12 days after i had sex i started bleeding very very lightly like i would only really see it when i wiped and it lasted about 3 1/2 days off and on and i was supposed to get my period yesterday and my periods are always really heavy atleast 1-2 days that i’m on ,, but now there’s no blood at all so i’m just confused
