After functional uterine bleeding, how is the menstrual cycle calculated?

Patient's question:

After functional uterine bleeding, how is the menstrual cycle calculated?
I had functional uterine bleeding on December 15th. Does the cycle start from the 15th? Is January 11th a safe period? Do I need to take emergency medication?

Doctor's answer:

It's the safe period, no need to take birth control pills.
