Implantation bleeding or early period?

Hi ladies,

First off, apologies for the picture. Then, I am curious your opinions… I will, obviously, give it time and have the answer, but I am curious. Do you think this looks like implantation bleeding or my period?

Some facts:

- 9 dpo today

- only teeny tiny cramping at front center of my uterus this morning, not much cramping otherwise, and no leg aches or back ache like I get with my period

- had diarrhea (again, sorry) about an hour ago. I’m sure this could also be period-related.

I guess if it’s my period, I have a short luteal phase bc I used an opk to predict ovulation this cycle and got the surge about 10 days ago.

Left was in my underwear, and right was a wipe.
