Is 31 too old to start having kids ?

I'll be 32 soon. I have no kids. My boyfriend and I have been together for five years and he doesn't ever want to marry or have more kids. He already has two. I am thinking of leaving because I want kids really bad.

If I leave , I'll be about 32. I'll of course need to date and meet a suitable partner. So I may not have kids til 34 or 35. Is that too old?

Wow ladies thank you for all of the kind words. I am from a small town in the South where women look down on you if you are childless. A place where everyone starts having their kids at 18.. really needed to hear this
