Implantation bleeding

Can any of you ladies tell me what your implantation bleeding looked like from personal experience?

I'm 7 dpo already curious if I could be pregnant because everything after ovulation was so different then normal for me this month. Then when I just wiped I noticed the lightest pinkish streak on the toilet paper. I wiped again and the same thing. It was so barely there that I wouldn't have noticed (but I've been looking each time taking note of the CM).
