Too young to be parents??

So I just need a little vent / advice ladies... my partner and I are both 22 years old, we’ve been married for a year and we own our own home. I’m a Registered Nurse working full time and hubby is a full time Plumber. We’ve always known we want to be young parents, and since the day we met we’ve always been on the same page and have never doubted our relationship. We are currently TTC baby number 1, we haven’t explicitly told many people but I find myself being told regularly that I’m far too young to have children. My in-laws always say things like “oh well way way way... down the track when you have children”. I find it so frustrating, we are married adults, we own our own home, we both earn a great living and have stable jobs. Anyone else in this boat? I’m so damn sick of it! I want our family and friends to be excited when we finally are pregnant!
