I can tell you one thing DO NOT do it at this young of an age. I'm 21 and considering it because my periods have been horrible my whole life. I literally have a week or two of pain and everything. I also hate kids though. I'm taking a couple more years to decide. Wait till you are at LEAST 18 years of age before making a decision like that. It's life changing and you can't go back. So just wait until you're an adult and then move on from there.
