11 dpo implementation bleeding?

Hi,

I’m 11 dpo. On 9 dpo i had some twinches in my right ovary. Today i whiped and was surprised by light pinkish bleed/cm with a strain or two or red. My period is due in 3-4 days. Now i am experiencing some light cramps. I was nauseus after lunch (could be the sandwich) and had bad fatigue (i did woke up early).

Could this be implantation bleeding or start of period? I usually do not spot, but if i do, it is more dark red-brownish.

I took the picture but only after several minutes and i believe color had oxydised (sorry, i am not native) so from picure it looks severe darker than it was in person. When i whiped it was really light pinkish.

Thanks
