Implantation bleeding or super early period?

Deana

Hey guys! Kind of freaking out over here. I’m 9DPO. First month really trying. Got a BFN this morning but wasn’t too concerned because it’s still so early. Then around 5pm I had some spotting when I went to the bathroom. According to Glo I’m not due for my period until May 4th (14 DPO) but according to my old period tracking app I’m due May 1st. I feel a little crampy/tired but from what I understand that could be period related or implantation related??
