Confused...

I got a positive ovulation test 6/30/2014 so 6 days ago today. I've been worn out for the past 3 days and tonight I check CM and it was super creamy looked like glue and was a white/yellow color. I went to the bathroom afterwards and when I wiped I notice red and pink spotting. I've had some light cramping but that's about it. Does anyone think it was implantation bleeding or what? My cervix last night was reachable but tonight I can't reach it at all. Still same CM.
