continuous birth control
There seems to be the almost universal belief among North American parents (I'm sure this is a phenomena found elsewhere as well, but I'm just talking about what I've personally seen) that their kids, whether these are theoretical future children or actual kids, and whether they have yet to reach their teen years or not, will hate or at the very least dislike them. Teenagers hate their parents: everyone knows that.
As you may know, at Scarleteen we do not yet endorse suppressing menstruation/continuous birth control -- using a hormonal method of birth control in order to skip withdrawal bleeds/periods -- for women under 18, because there still is yet to be any study done or published with adolescent women to evaluate if it is safe or medically sound for those in that stage of physical development.
There is yet no available data concerning the long term effects of menstrual suppression on a woman's overall health, at any age. I should also mention that no studies have been published yet about the safety or efficacy of suppressing periods with the patch or vaginal ring.
However, there have been published and reviewed studies for women over 18 using oral contraceptives for suppression.
