Implantation bleeding or period?

Kaitlin

I’m 10DPO and last night after I went to the bathroom I had some red blood on the toilet paper. I woke up this morning and there was nothing.. I feel like this is too early to get my period as mine usually range from 30-32 days. Today marks cycle day 28. I will attach my BBT chart. Can anyone give me input? I had no sign of my period coming so I’m confused if this is implantation bleeding. TIA
