Help please!

I started my birth control on Nov. 8th and got my period at the 3 week point for a straight 7-8 days and not during my sugar pills. Once I was on the sugar pills I spotted once on the third day then haven't ever since. It's been about 5 days since the sugar pills and I haven't had a period. Is that bad? Could this mean I'm pregnant because I didn't get my period on my sugar pills or was it just because I got my period early? 
Thanks in advance !
