Surrogacy

I’m only 17 right now so I’m not able to become a surrogate yet. But I’ve really been thinking about it lately. I loved being pregnant and it’d be amazing being able to give someone a family. I mentioned it to my boyfriend and he wasn’t supportive of it AT ALL. I mean obviously I’ve still got a few years to think about it and stuff and who knows if he’ll even be anything more then my daughters father by then. But what could I do to get him to support me on it? Cause I really want to be a surrogate when I’m old enough
