Period stopped with Nuvaring - just started BC again

I have started the Nuvaring 2 days ago, on the first day of my period. As the first two days are always pretty light for me, I though that my period will fullyehit me today. However, when I checked my menstrual cup, there was no blood, only some cervical mucus. Did the start of the Nuvaring stop my period? Or should I be prepared in case I get a full blown period after all?

I haven't used BC for over 2 years. Before, I was on it for 7 years.
