Period? Implantation bleeding?

Carmen
I have a very long cycle (40-41 days). I took Clomid Days 3-7 of my last cycle which was in August. Due to my long cycle and the way the dates fell I didn't have a period in September. My October period was suppose to arrive on October 6th. October 8th I had a little blood that was bright red, everything on the pad after that was brown and like a discharge. I have not had anything since Friday morning. Was that implantation bleeding?? Should I test??
