Nexplanon Removed what too expect?

I Had My Implant Removed on 11/7/16 and it's been 3 days and this morning I woke up and used the bathroom and there was light blood so I went to school not thinking about it and it was enough blood to make my under wear feel wet so I put a pad on and I just had brown spotting maybe old blood? But now it's back to light blood really light i don't think I'm on my period but I'm not sure what it is... I'm cramping Too  on scale 1-10.(10 being worst) I'm feeling a 6.. what could this be? Tell me your after removal stories
