Early implantation?

Alright everyone, I need some help! So I just got off my period last Wednesday night, we BD two days before my period started, the day after my period ended, Saturday, Sunday, and yesterday (were really active this time😂). I’ve been cramping most of the day, but I had a little bit of blood in my CM when I just went to the bathroom which has never happened, unless I’m on my period. I know implantation bleeding is normal but I have no clue how that is even possible when it hasn’t even been a week since my period is done unless I got pregnant the two days before my period and somehow still had a period?? I’m so confused just because it’s weird for me to have any kind of spotting😂🤷🏼‍♀️ any tips would be appreciated!
