Help?

(TMI btw) Okay so I have a two periods a month, my period ended the 22 since my periods are so crazy I ovulate differently instead of 5 days after it’s 1 I have an app too that helps me. So I stopped my period the 22nd and on the 23 I had light brown spotting as well as once a little red when I used the bathroom from there I had sex the 24th and 25th my ovulation day was the 26th. Then the 28th-30th I had cramping and fatigue from then the 31st and today I’ve had spotting. My second period starts the 8th. I took a pt today and it came back negative but I think it might be too soon. Wondering if the spotting was maybe implantion and the brown/red discharge after my period was ovulation spotting lol. Been spotting for four days now on/ off only when I wipe and goes from light very light pink to light brown
