What Should I Say to My Mother?

I have a unique situation that I feel like is really normal. Me and the love of my life (seriously 😍😍😍) have been together for 9 months. Things are great and we're talking about getting married. But my mother got married to my dad when she was 19 after only 3 months of knowing him and she keeps criticising us for not being married yet. I keep trying to tell her that we don't even have the money to move yet and we would have to live apart even if we did get married now. it's driving me crazy and making me feel trapped and pressured. It's enough that everybody I meet asks me why I don't have kids yet because of my age. Is there anything I can do about this?
