Can implantation bleeding have tiny clots or tissue?

Terrified I'm pregnant and not ready. I'm about 10 dpo and only 3 weeks 3 days from day 1 of my last period. I started spotting very light pink but I saw really tiny chunks in the toilet (like inch worm size lol) and wondering if it's maybe just the start of my period.

I took a test today and it was negative but I'm still freaking out 😩
