birth control wont make you infertile. some women just in general i think have a harder time after they end birth control because their bodies need time to adjust to the ovulation cycle again. or they may not be having sex at their most fertile time of the month. but i dont think there are any kind that end your ability to have children. because they have to be approved by like the fda or something before going on the market. they may have even had problems before birth control started where they werent very fertile to begin with and thought the birth control made them infertile. thats always possible i suppose
