implantation or period?

idk if this is implantation or my period being weird as hell this month. my period is due for another 2 days and my last period was november 2nd. i had unprotected sex 18th-19th. i apparently ovulated around that time but i only went by the app so it most likely was wrong lol. the issue is that im having this kind of bleeding but its not consistent. at first it was like a gush of blood, now it only appears when i wipe. it varies from darker to bright red blood. super confused. i’m taking a pregnancy test in the morning but id like to know if anyone else’s periods have stopped then started and stopped and started again? update now im barely bleeding but it’s still the same color as the pic when i do spot
