Implantion bleeding????

Katelyn
Ok I'm confused I'm not supposed to start for 10 to 13 days but this morning I went to the bathroom and had dark (light blood) on it mixed in with my cm and I wiped again and it was pink then it was clear with a swish of blood then nothing a couple hours later it was clear and streachy and light light light brown and now nothing again! What's going on?
