should i stop taking femcon???

i have been on Femcon for 5 months. i am not due to have my period until February 10th or 11th. i have been bleeding heavily since Saturday, February 2nd. i have 2 more active pills to take until my placebos. my question is do you think i should stop taking them or get me another pack and see what happens. i am scared because i don't know why i have been bleeding like this, 1 week prior to my period. i am just confused and don't know if i should switch pills, stop taking them all together or what??!!!
