The beginning i bled a lot, 40 plus day periods with few breaks in between. After about a year my periods went away and I only have spotting now. I recently found out I should only be using this form for no more than 2 years but this is my best option. It has been affecting my bones because I experience pain in my knees and hips that I haven't before this birth control. It does control my acne and is reliable which is a plus for me, i haven't experienced weight gain which is a common side effect. I have migraines more often after my shot and leading up to it as well. Overall I don't care for birth control in general and will be looking for other options.
