Weird spotting??

Marissa

So I stopped nuva ring on July 11th had my bleed from the 13-17 (normal for me) I was doing OPKs from cd 6-14 and got a positive OPK the 25th. Then the 31st the 1st and the 3rd I was spotting brown randomly through the day (and not constant) not enough to get on my panties only when I wiped.. them today when I woke up I was spotting light pink (12dpo) and thought I was starting my period today but it's been 4hrs now of nothing... my projected period is the 8th and ive never had spotting randomly ever anyone know what it could be I know stopping bc can do weird things to your body but I've stopped it before and it's never made me spot so weirdly....
