Been having break through bleeding for almost three weeks of starting birth control micrognon for the first time. .how can i make it stop?

Change birth control: It may take a woman's body time to adjust to a new birth control method, and if you are not bleeding heavily it is safe for you to continue the Micrognon another month. However, you may need a different combination of hormones to prevent the breakthrough bleeding. You should contact the provider who prescribed the Micrognon and discuss your options.
