Title: The Effect of Text Message Reminders on Contraceptive Continuation, a Randomized Controlled Trial
Brief Summary: Teen girls and young women taking birth control pills may forget to take their pills or may stop taking them altogether. This places them at risk for unintended pregnancies. Most young women own cell phones and use them for text messaging. We will test whether contraceptive continuation is affected after six months of daily text message reminders.
