Fertility

How long after coming off birth control did you fall pregnant? I don’t have any fertility problems that I’m aware of but it’s now been 9 months. I’m early 20s so shouldn’t be a problem? I know people say wait at least a year or 2 before worrying but I can’t help but be concerned. Did any of you have to wait a long time without having any fertility problems or is this a sign that I could have fertility problems?
