I've been off bc sprintec since may and bled twice each month until this month i had a normal period what does that mean?

Birth control: It means your menstrual cycle is gradually coming back to its normal pattern. This can vary in time from individual to individual.

Not much : After coming off birth-control it may take a few months for your cycles to regulate. If you continue to be a irregular off birth-control then consider restarting. Birth-control is excellent giving regular periods.
