Implantation? Pic included. TMI!

Tiffany • 25 years old. Baby #3 due August 17!

My period is due in 6 days. I took a test yesterday knowing it would be too early which was negative but today I have this. Do you think it’s implantation bleeding or start of period? I rarely ever bleed before my period. I am 8 days post ovulation. Light cramping. I can’t remember if I had this with my first. Thanks in advance!
