That's the whole Point, most people do not Realize Or Accept that Birth Control is used by Women for more then just Presenting them from getting Pregnant, it is for a Myriad of other Allements, I know people who receive Anti Deressents and the Filler card says "This Medication is to Treat the Symptoms of Depression OR OTHER MEDICAL ISSUES AS DIRECTED BY THEIR DOCTOR" so you can be on an Anti Deprssent not be Bi Polar but stil beneift from the Chemical Makeup of the Medciation
Women do use birth control for reasons beyond just not getting pregnant
