"had since 10/15. definitely works as birth control. but thats only when i can give it the purpose of being birth control. i&#039;ll have a heavy period for a week to a week and a half then it&#039;ll break for a couple days, then i&#039;ll start again, but lighter. then break for a couple days, then start again but lighter. this will keep going for a few weeks until i&#039;ll be free for maybe a week, until it starts again from the top. i haven&#039;t had some of the more severe side effects, but it seems to be an inconvenience when i have to worry about if im bleeding through my pants, especially when it&#039;s summer and i&#039;m always out and about or working, and i dont always remember to grab tampons or pantiliners. it was pretty regular the first few months though..."
