Had my period for 10 days almost 2 weeks when i usually have it for 5 days. i started taking my birth control pill then stopped for a while?

Irregular Menses: It is common for young women to have irregular menstrual cycles: have their periods last longer, come late or miss them all together. In ur case it is probably due to a hormone imbalance from starting then stopping ur birth control pills. Consider restarting the pill or other hormonal contraceptive, especially if your sexually active. Otherwise, your cycles should normalize within a few months.
