I want to start on birth control but I've been too nervous to for the past few months. I'm not nervous about the birth control it self and it changing my hormones per say, just how it will react with my body. I'm scared of a negative reaction and the consequences that'll go along with it. I know a few people that have gone sterile (idk if sterile is the proper term for females) after starting different types and that's the only thing that scares me. I want to have kids someday and I don't want to make a mistake on birth control and have it effect my fertility in the future. How do you find out what will work best for you?
