Getting Pregnant

So I just stopped taking my birth control about a month ago. My boyfriend and I decided that we were ready to have a baby. Well, he decided. I've wanted a baby for the three years we've been together. Lol. He's 34, I'm 22. He's got a six year old boy so I know he'll be a great father. AND we've been looking at engagement rings. But my question is... Is it as hard as all the medical websites make it sound to get pregnant right off birth control? Like will it legitimately take us a year? I just started taking a women's multivitamin about two weeks ago and I'm keeping close track of my cycle now that I don't have my little birth control pill pack to tell me when I'm getting my period. Should I be doing more to increase my chances of getting pregnant? Is there more I can do to increase me chances of getting pregnant?
