Yes, I think that teenage girls should be allowed to get birth control without the permission of their parents because they have a right to their body. If a girl has gotten sexually active in the past and knows that she will be getting sexually active in the future and wants to protect herself from unexpected pregnancy, then yes.
Birth control is used for so many things other than for the purpose of controlling birth. It is possible for a teenage girl to get medication for other problems she might have so why not for intense menstral cramps, which is one thing birth control pills help. It should be allowed.
Birth control is used for a variety of different things. Medical, menstrual, and then pregnancy prevention. I personally am not sexually active. BUT I AM ON BIRTH CONTROL. For medical reasons. I don't understand what this whole controversy is. Birth control is only for the good. It should not be frowned upon.
