Want a kid

My boyfriend and I are ready for a kid, but we are still in school, we are almost done with it, and one day he told me he wanted a kid and I told him the same thing, we looked at all the pros and cons, and we maturely talked about it and decided we are ready.. the problem is.. I am on birth control and I don’t know how to tell my doctor that I’m ready for a kid... 😬... I need advice
