20 and ready

I always see all of my friends posts about being engaged, being pregnant, or just having a baby. It's everywhere in my life right now because all of my friends are going through this. I just turned 20 my bf is 19. We've only been together for 5 months and we are so close as lovers and best friends. Is it abnormal to say I'm ready to have a baby and get engaged with him? I swear I'm not one of those immature little girls posting lol but seriously.... Is it crazy I'm ready to start my life with him already? I'm in nursing school, we'll still in community college going to transfer, he has a full time job with overtime and double time. Idk I'm just ready to start my life with him 🙈💞💍
