If this is the first time that you started birth control pills, then sometimes it takes 3 months for your body to get used to it. Once you start the birth control pills, then you should take a pill everyday. For the spotting, you can try ibuprofen 600 mg up to 3 times a day for up to 5 days WITH FOOD to see if that helps. It would have been better if you started on the LAST day of your bleeding but it’s ok to start when you started.
