Can birth control build your spell 12 days+ ?
Answers: yes, this is a adjectives when taking BC pills
birth control will make ur period do that for the first few months until ur body gets used to it and go to the regular pattern...nought to worry more or less = ) spotting between periods is exceedingly common on birth control pills. Always kind sure you read the little pamphlet that comes with your pills because it answers MANY question, such as this one. If you have continual bleeding, it is suggested that you preserve on taking your pills, but make an appt near your doctor to discuss why this may be happening.
It sounds to me similar to you went straight from one pack to the subsequent without taking your ordinary "break" between packs. If you did this, this will also save up your bleeding pattern because here was no removal of hormones. This is vastly common when this is done and frequent experience this (some doctors will tell patients to bring 3 packs continuosly and next have their weeks' "break" to enjoy a period to help out relieve pain...it is customarily for females who are suffering from horrid period distress and/or endometriosis). I could be wrong, but that is how I interpreted what you said.
I'd dally a little while longer and see if it go away. If not, make an appt next to the doctor, but keep taking your pills. It could simply be because you go straight onto your next pack. :)
