I took Cerazette for over 1 year and now I've had bleeding?

I've taken the contraceptive Cerazette for over 1 year without a break! My period has not come for a while. But now it's coming down ... is it normal? Should I take the contraceptive anyway?
Expert answer:

Possible bleeding may occur, you should continue with the contraceptive if you do not want to have a baby.
