enjoy life now!
Take it from an "old" lady with two kids: You are too young now to have a baby in your arms. Okay, back in the 1800's women had several kids by this time, but this is not the 1800's!!!
The time is right when you feel you and your man have lived your life together as a married couple long enough to feel that an extra life that demands constantly
isn't going to interfere with or cramp your lifestyle. Just ignore the busybodies and say something like "When I choose to have them, you'll be the first to know."
I had my first child when I was 28. I had my second when I was 30. Life changes drastically when you have a child, and even more so when you have two. I was very glad that I waited until I was in my late 20's to become pregnant, because once you have children, realize that you will have them for many years and your whole life will be based around them until they are at least 18, and probably beyond. So, having a child isn't something that just anybody (especially the busybody) is going to decide for you.
I am sure that when the time is right, you will get the urge.
