Implantation bleeding (tmi)

So I'm just wondering if this is normal or if I should be worried. I started dark brown to black spotting about 5 days ago and it shows no sign of stopping... I read that implantation bleeding should only really be one to two days of bleeding. I'm just worried because I had a MC in March and I need to watch out for unusual signs. The picture looks pinkier than the spotting actually is, it dark brown for sure. Is this normal? Also when I took my four tests I peed into something and there was tiny little floating clots. Just about visible? Is that normal too? I only mention it just in case.
