Stopping birth control, then starting again?

I have been on yaz for 4 months and stopped taking it 6 days ago because I lost the pack and couldn't get another pack until today. I started bleeding yesterday, but it is very light and seems like it might stop soon. My question is, do I start my pills again Sunday? Or wait until a real period starts? I'm thinking this is just with drawl bleeding.. or does it matter? I know you're suppose to take it the sunday after your periods starts but i'm not sure if i should consider this a period? HELP?
