So my family has a history of having troubles getting pregnant. As far as I know, none of them used birth control. I'm not sure if I really want to have kids in the future, but if I end up wanting to I don't want to make things more difficult than they possibly/probably already will be. So many people I know who were on birth control for a number of years that want to get pregnant now are struggling and I just don't want to be like them.

My question is what has people with similar pregnancy issues used birth control and not had many/if any at all complications getting pregnant and having kids?
