My fiance wants to start a family with me

And I want a family with him too. I'm just a little nervous about it. I don't know the process of coming off birth control pills, if I need to ween off them, stop at the end of a pack, or could just stop taking them whenever. There's so many thoughts that are racing through my mind about it. I have anxiety so there's a lot of "what if" going through my brain right now, imagining all the things that could go wrong. Like: What if I can't get pregnant? I've been on birth control nonstop for several years, will that affect my ability to have babies? Those kinds of questions.

Any advice for a young lady who's eager to start a family with her man, but also really anxious? What kinds of things did you guys think when you were trying for babies? How did you prepare for it mentally? Especially when that first period showed up after you started trying? How did you push through the disappointment?
