Implantation bleeding?

The past 3 days I've had spotting that was Brown with a little light pink color... Definitely not enough to fill a tampon and isn't on a pad or panty liner.. I've only seen it when I've taken my tampon out.. reason I wear a tampon is because I thought I was getting my period.. I had cramps and super bloated and gassy.. I have no idea when I ovulated. My periods are whacky.. I would like to hear other peoples input 😁
