So should we even bother to have children at this point; knowing what we know?
Of course.
Jesus said: "Occupy til' I come".
I'm also reminded of the two men who were lepers and the who said, "Why sit we here til' we die?"
If we just sit and 'not live' then we will not live. We will only waste the beautiful moments of life in fear, doubt, and worry. What kind of quality of life is that, especially when we still do not know the time, the day or the hour when the 'end' will come?
God said, 'Choose Life'. Choose life by choosing to follow Him and His word and to live in the fullness of life. Jesus said that He came to give us life and to give it to us more abundantly. This means life here on earth as well as in eternity with Him.
So indeed, get married....have your babies...continue with your education (we still need knowledge to endure and to overcome the world - rebuke satan and undermine his exploits), and occupy the world ... enjoy this life, love and bring others to Him to know and to love Him, build and maintain Churches, raise our children to know and to love God... all of this and even more until Jesus comes. That's what He's commanded us to do.
