Early period?

Kail • I`m 24 and a nursing student. I got married on October 8, 2015. I have PCOS.
I take my Nuvaring out on Fridays and usually my period arrives the following Wednesday. Today when I went to the bathroom, I noticed some blood. I don't know if this is my period or not? 
Perhaps this is a silly question. Has anyone else experienced this on NuvaRing?
