Anyone else hate the "you need to wait a couple of years to try for a baby" speech?

So im 19 years old. I got married last month to my best friend for 5 years. Everyone is already giving me shit for getting married at 19. Well I want a baby and i haven't mentioned that to anyone except my husband. He wants a baby just as bad as I do. Well every time someone says congratulations its usually followed by "you need to just wait to have children though. You need to live your life first before you get tied to a baby". Ok seriously I could go on a huge giant rant about how wrong that is for them to say and its my freaking life, but im not going there. Im just wondering if anyone else has this frustration as well?
